In this way, how do you determine if a solution is acidic or basic?
A solution with a pH of 7 is classifiedasneutral. If the pH is lower than 7, the solutionisacidic. When pH is higher than 7, the solutionisbasic. These numbers describe the concentration ofhydrogenions in the solution and increase on a negativelogarithmicscale.
One may also ask, how do you know if a salt is acidic or basic? The pH of a solution reflects the concentration ofH3O+ions. A pH less than 7 indicates an acidic solution, apHgreater than 7 indicates a basic solution, and a pH of7indicates a neutral solution. Acidic saltsmakeacidic solutions and basic salts makebasicsolutions.
Keeping this in view, how do you determine if an acid is strong or weak?
If an acid is not listed here, it is aweakacid. It may be 1% ionized or 99% ionized, but it isstillclassified as a weak acid. Any acid thatdissociates100% into ions is called a strong acid. Ifit doesnot dissociate 100%, it is a weak acid.
Is LiOH an acid or base?
No, LiOH is a strong base, like theotheralkali bases. It is a bit weaker than bases likeNaOHthough, because it's enthalpy of formation is different.Itsconjugate acid, Li+, can act as a weakLewisacid.
