The acetic acid (HC2H3O2) found in the vinegar will react with the NaOH until all of the acetic acid is neutralized. When an acid, such as acetic acid reacts with a base like NaOH, the products are a salt (NaC2H3O2, sodium acetate) and water (H2O). This means you have 25.00 g of vinegar in your flask.

ExplainerWhat reacts with sodium hydroxide?
Chemical properties
The hydroxide ion makes sodium hydroxide a strong base which reacts with acids to form water and the corresponding salts, e.g., with hydrochloric acid, sodium chloride is formed: NaOH( aq) + HCl(aq) → NaCl(aq) + H2O( l)

ExplainerWhat happens when you add phenolphthalein to sodium hydroxide?
Explanation: When the sodium hydroxide, which is a base, is mixed with phenolphthalein, it turns pink. This happens because the base is neutralized in an acid solution, which causes the indicator to become colorless.

ExplainerWhat salt is formed of acetic acid reacts with sodium hydroxide?
Neutralization reactions are the reactions in which acid reacts with base to form salt and water. So Acetic acid (CH3COOH) reacts with Sodium Hydroxide(NaOH) to form Sodium Acetate (CH3COONa) salt and water(H2O).

ExplainerIs acetic acid and sodium hydroxide a buffer?
A mixture of acetic acid and sodium acetate is acidic because the Ka of acetic acid is greater than the Kb of its conjugate base acetate. It is a buffer because it contains both the weak acid and its salt. If we add a base such as sodium hydroxide, the hydroxide ions react with the few hydronium ions present.

ExplainerWhat is the Colour of phenolphthalein in neutral solution?
For this application, it turns colorless in acidic solutions and red in basic solutions. It belongs to the class of dyes known as phthalein dyes. Phenolphthalein is slightly soluble in water and usually is dissolved in alcohols for use in experiments. It is a weak acid, which can lose H+ ions in solution.

ExplainerWhich indicator is best for titration?
A strong acid- strong base titration is performed using a phenolphthalein indicator. Phenolphtalein is chosen because it changes color in a pH range between 8.3 – 10.

ExplainerAt what pH does phenolphthalein turn pink?
Phenolphthalein works somewhat differently as it is naturally colorless but turns pink in alkaline solutions. The compounds remains colorless throughout the range of acidic pH levels but begins to turn pink at a pH level of 8.2 and continues to a bright purple in stronger alkalines.

Shaomei Einhaus
ExplainerWhy does phenolphthalein turn pink in sodium hydroxide?
The pink colour of the solution is due to the concentration of ions in the solution. At this point, no Titrand (NaOH) is added to the solution. Therefore, Phenolphthalein is under acidic conditions and hence it is colourless. This solution is now titrated against Titrand ( NaOH).
Minka Pividal
ExplainerIs phenolphthalein a natural indicator?
Phenolphthalein. Phenolphthalein, (C20H14O4), an organic compound of the phthalein family that is widely employed as an acid-base indicator. As an indicator of a solution's pH, phenolphthalein is colourless below pH 8.5 and attains a pink to deep red hue above pH 9.0.
Jannet Batsev
ExplainerWhy do we need to standardize NaOH?
First of all, solid NaOH absorbs water from the air, so accurately weighing a sample during the preparation of a solution is impossible. Standardization is typically carried out by titrating the NaOH solution with a primary standard, an ultra-pure, easily soluble acid such as potassium hydrogen phthalate (KHP).
Ollie Bagautdinov
ExplainerIs NaOH an acid or base?
NaOH, or sodium hydroxide, is a compound. A compound is classified as either an acid, base, or salt. All bases contain OH- (hydroxide) ions, while all acids contain H+ (hydrogen) ions. A salt is a compound that is formed when a base and an acid are combined because they neutralize each other.
Alzira Grohotov
ExplainerWhat is it called when the indicator changes color?
An acid-base indicator (e.g., phenolphthalein) changes color depending on the pH. Redox indicators are also frequently used. A drop of indicator solution is added to the titration at the start; when the color changes the endpoint has been reached, this is an approximation of the equivalence point.

Souria Macdermott
ExplainerIs HCl a strong acid?
A strong acid is an acid which is completely ionized in an aqueous solution. Hydrogen chloride (HCl) ionizes completely into hydrogen ions and chloride ions in water. Weak acids, like strong acids, ionize to yield the H+ ion and a conjugate base. Because HCl is a strong acid, its conjugate base (Cl−) is extremely weak.

ExplainerWhat does sodium hydroxide and Ethanoic acid make?
It is an acid=base reaction. The word equation is. Acid + Base → Salt + Water. so, ethanoic acid + sodium hydroxide → sodium ethanoate + water.
Annabel Binner
ExplainerWhat happens when acetic acid is dissolved in water?
Acetic acid is extremely soluble in water, but most of the compound dissolves into molecules, rendering it a weak electrolyte. However, acetic acid is able to form many new hydrogen bonds to water molecules and so this results in a highly favourable interaction, leading to the high solubility of acetic acid in water.

ExplainerIs koh a strong base?
KOH is potassium hydroxide. Since it is composed of the hydroxide anion (OH-), it is a strong base. The two ions (K+ and OH-) completely ionize in water. So KOH is both a strong base and a salt.
Aurelia Jorro
ExplainerIs NaOH a strong base?
Sodium hydroxide (NaOH) is strong base because it fully dissociates in water to produce hydroxide ions. While weak bases produce fewer hydroxide ions, making the solution less basic.
Laurenta Lajoso
ExplainerWhat is the PKA of acetic acid?
Acetic acid is a weak monoprotic acid. In aqueous solution, it has a pKa value of 4.76. Its conjugate base is acetate (CH3COO−). A 1.0 M solution (about the concentration of domestic vinegar) has a pH of 2.4, indicating that merely 0.4% of the acetic acid molecules are dissociated.
Jann Diekhoff
ExplainerIs HCl a buffer?
Hydrochloric acid (HCl) is a strong acid, not a weak acid, so the combination of these two solutes would not make a buffer solution. Ammonia (NH 3) is a weak base, but NaOH is a strong base.
Yannik Fogg
ExplainerIs water a buffer?
Water is a buffer albeit a poor one. This is because H20 seelf ionises to form H30+ and OH-. To form an acidic buffer buffer you need a weak acid with the conjugate base. As there will be hydronium and hydroxide ions present yes it acts as a buffer but is a horrible one.
Edvard Sunanda
ExplainerWhat is buffer equation?
The equation can be derived from the formula of pKa for a weak acid or buffer. The balanced equation for an acid dissociation is: HA⇌H++A− The acid dissociation constant is: Ka=[H+][A−][HA]
Kunal Belzhause
ExplainerHow do I calculate pKa?
To create a more manageable number, chemists define the pKa value as the negative logarithm of the Ka value: pKa = -log Ka. If you already know the pKa value for an acid and you need the Ka value, you find it by taking the antilog. In practice, this means raising both sides of the equality to exponents of 10.
Devorah Gretschmann
ExplainerIs HCl and NaOH a buffer system?
E.g., HCl (strong acid) and NaOH (strong base) will react together to form H20 and NaCl (salt). When there is a mixture of a weak acid and its conjugate salt (or weak base and its conjugate salt) a buffer is formed.
Maixa Mahtani
ExplainerIs sodium hydroxide a buffer?
For alkaline buffers, a strong base such as sodium hydroxide may be added. Alternatively, a buffer mixture can be made from a mixture of an acid and its conjugate base. For example, an acetate buffer can be made from a mixture of acetic acid and sodium acetate.
Trista Antonopoulos
ExplainerHow do you calculate the pH of a mixture?
Substitute the pKa of the acid (4.74 for acetic acid) and the acid and base concentrations into the Henderson-Hasselbalch equation to calculate the pH of the buffer solution. For example, pH = 4.74 + log (0.0025/0.005) = 4.74 + log 0.5 = 4.44.
Leola Balanowsky
ExplainerHow do you calculate buffer solution?
To calculate the specific pH of a given buffer, you need to use the Henderson-Hasselbalch equation for acidic buffers: "pH = pKa + log10([A-]/[HA])," where Ka is the "dissociation constant" for the weak acid, [A-] is the concentration of conjugate base and [HA] is the concentration of the weak acid.
