Which compound is more soluble in an acidic solution than in a neutral solution?

Answer : Salt is more soluble in an acidic solution than in an neutral solution.

Explaination : In an acidic solution molecules of salt are assaociated with hydrogen bonding whereas in neutral solutions it molecules are not assaociated with hydrogen bonding. Acidic solution is a type of solution which has higher concentration of hydrogen ions than water is called acidic solution for ex: water.

Neutral solution is a solution which has a pH of 7, it is neither acidic nor basic but it is middle so that is called neutral solution.
