Why is NaCl more conductive than CaCl2?

Last Updated: 31st May, 2021

Because NaCl has two ions, CaCl2 has 3 ions, and AlCl3 has 4 ions, AlCl3 would be the most concentrated with the highest conductivity and NaCl would be the least concentrated with the lowest conductivity. Because it dissociates fully, it'll produce more ions in water.

Also question is, is CaCl2 a good conductor of electricity?

The density of calcium chloride is 2.15 gm/cm3. It is soluble both in inorganic solvents like water, as well as organic solvents like ethanol. Usually in a molten state, it is a good conductor of electricity. Calcium chloride is a bad conductor of heat.

Subsequently, question is, why is NaCl conductive in water? Common table salt (NaCl) is an electrolyte, and when this is dissolved in water to form salt water, it becomes sodium ions (Na+) and chloride ions (Cl-), each of which is a corpuscle that conducts electricity. In water, it is the ions that pass electricity from one to the next.

Likewise, why is KCl more conductive than NaCl?

It will be Li>Na>K Smaller the size, more the equivalent ionic conductance. That is only one force, the K+ ion is larger than the Na+ ion, so the distance between the K+ and Cl- ions is greater than between Na+ and Cl-, decreasing the bond strength. Yes, KCl has a high bond energy, but not as high as NaCl.

What is the conductivity of NaCl?

The conversion of conductivity to the total dissolved solids depends on the chemical composition of the sample and can vary between 0.54 and 0.96. Typically, the conversion is done assuming that the solid is sodium chloride, i.e., 1 μS/cm is then equivalent to about 0.64 mg of NaCl per kg of water.

Why ccl4 is not a good conductor?

Compound like ccl4 have non polar bonds due to which it is not soluble in water which is polar in nature thus no ions are released and no electricity is conducted.

Can methanol conduct electricity?

In reality, a solution of methanol and water does conduct electricity, just to a MUCH lower extent than a solution of HCl in water. The self-ionisation constant of methanol will be very low, it will be only marginally different to that of water (which is about 10−14 .

Is CaCl2 conductive in water?

Electrolytes are dissolved ions. Aqueous solutions of ionic compounds such as NaCl or CaCl2 are able to conduct electricity. Not all chemical compounds behave this way, however. If sugar is dissolved in water the solution that results is not electrically conductive.

Is citric acid conductive in water?

Citric acid is not a good conductor of electricity.
This is because it is an example of a weak acid, which breaks down in water quickly. Citric acid only produces relatively few ions, making it a weak conductor for electricity. On the other hand, strong acids conduct electricity very well.

Is ethanol a conductor?

No, ethanol does not conduct electricity. Ethanol does not dissociate in this way; the bond between the oxygen atom and the hydrogen atom in the -OH group is much stronger. Without free ions, there is no mechanism for transporting electrical charge and the electrical conductivity is zero.

Is NaCl an electrolyte?

NaCl is an ionic compound. Since it dissolves completely forming Na^+ and Cl^- ions it is classified as a strong electrolyte. Strong electrolytes are completely dissociated into ions in solution and conduct an electrical current strongly that is, they completely ionize in water and are good conductors of electricity.

Abdoulaye Shadyev


Is Sugar an electrolyte?

Strong electrolytes are substances that completely break apart into ions when dissolved. The most familiar example of a strong electrolyte is table salt, sodium chloride. Sugar, for example, dissolves readily in water, but remains in the water as molecules, not as ions. Sugar is classified as a non-electrolyte.

Is ethanol an electrolyte?

An electrolyte is a compound that conducts an electric current when it is in an aqueous solution or melted. Many molecular compounds, such as sugar or ethanol, are nonelectrolytes. When these compounds dissolve in water, they do not produce ions.

Can NaCl conduct electricity?

Solid sodium chloride doesn't conduct electricity, because there are no electrons which are free to move. Now, mix it in water and place the two leads from the battery and the below things happens: As soon as the salt is mixed in water, we get Na+ and Cl- ions.

How can you make water more conductive?

For making water a Good conductor acidify it with any strong acid such as Sulphuric acid, Hydrochloric acid etc. Only small amount of acid is needed. Due to which the bonds between water molecule breaks and it conducts electric current.

Nichelle Manzaneda


What happens when electricity is passed through NaCl?

When an electric current is passed through concentrated sodium chloride solution, hydrogen gas forms at the negative electrode , chlorine gas forms at the positive electrode, and a solution of sodium hydroxide also forms. However, sodium is too reactive for this to happen so hydrogen is given off instead.

Is water a conductor?

What makes water a good conductor of electricity? Pure water is a poor conductor of electricity, but the water in oceans lakes and rivers always contains dissolved salts. Salts are formed with ionic bonds, and when dissolved in water, the ions are separated by the electric fields of the polar ends of water molecules.

Benjami Arendt


Why does NaCl have high conductivity?

When you put electrodes in the solution, the cations are drawn to the cathode and the anions to the anode. This movement produces a current and that is why NaCl solutions can conduct electricity. NaCl is strongly ionic compound. Presence of +ve and -ve ions helps in conduction of electricity.

Is sucrose conductive in water?

All of the bonds in the sucrose molecule are strong covalent bonds. Therefore there are no charged particles present to conduct electricity either in the solid state or in solution. Substances like sucrose which do not conduct electricity in aqueous solution are called non-electrolytes.
