A salt is an ionic compound that is produced when a cation and an anion from an acid-base reaction combine. In other words, the cation from a base replaces a proton on an acid.An example is the reaction of the strong base NaOH with the strong acid HCl. In solution, the H+ and OH− ions react to form H2O, leaving a solution of salt ions, Na+ and Cl−. In this example, the salt ions do not affect the pH of the solution and are, therefore, said to be spectator ions. The conjugate base of a strong acid is always a weak base (and the conjugate acid of a strong base is always a weak acid). So the conjugate base Cl− of the strong acid HCl is always a weak base and the conjugate acid Na+ of a strong base NaOH is always a weak acid.However, anions from weak acids and cations from weak bases change the pH of an aqueous solution. If one of the salt ions is the conjugate acid of a weak base, the ion will react with H2O to create H3O+ ions, acidifying the solution. Similarly, the conjugate base of a weak acid will react with H2O to create OH− ions, making the solution more alkaline.It can also happen that both of the ions in the salt can react with H2O. In this case, the pH of the solution can be more difficult to predict, and it depends on the extent to which each of the ions hydrolyzes (reacts with water). Part AClassify each salt as acidic, basic, or neutral.Drag the appropriate items to their respective bins.KNO3 LiCN NH4ClNEUTRAL SALTS ACIDIC SALTS BASIC SALTS

Answer:

KNO3 (neutral salt);  LiCN (basic salt); NH4Cl (acid salt)

Explanation:

KNO3 →  K+  +  NO3-

K+ comes from KOH, an strong base so it's the weak conjugate acid

NO3- comes from HNO3, an strong acid so it's the weak conjugate base

In water, they do not make hydrolisis so the salt is neutral.

LiCN → Li+  +  CN-

Li+ comes from LiOH, an strong base so it's the weak conjugate acid

CN- comes from HCN, a weak acid, so it's the strong conjugate base

In water Li+ doesn't make hydrolisis, but cyanide does.

CN-  +  H2O ⇄  HCN  +  OH-

This is a basic salt

NH4Cl → NH4+  +  Cl-

NH4+ comes from the  ammonia (NH3), a weak base, so it's the strong conjugate acid.

Cl- comes from the HCl, an strong acid, so it's the weak conjugate base. In water it doesn't make hydrolisis.

As the NH4+ does make hydrolisis, the salt is acid.

NH4+  +  H2O ⇄  NH3  +  H3O+
