Answer 1

Answer #1

Sol: Option D

First of all we need to figure out how Ca(NO₃)₂ salt is formed. The pH of an aqueous solution of salt is determined by the following rules.

Salts formed by the reaction of a strong acid & weak base would be acidic in nature with pH<7
Salts formed by the reaction of a weak acid & strong base would be basic in nature with pH>7
Salts formed by the reaction of a strong acid & strong base would be neutral with pH=7

Lets look at how Ca(NO₃)₂ is formed

Ca(OH)₂ + HNO₃ = Ca(NO₃)₂ + H₂O

Ca(OH)₂ is a strong base & HNO₃ is a strong acid so we can clearly understand that the aqueous solution of Ca(NO₃)₂ salt is neutral.

Option A is wrong as it fits into salts formed by the reaction of a strong acid & weak base.
Option B is wrong as it fits into salts formed by the reaction of a weak acid & strong base.
Option C is wrong as Ca(NO₃)₂ dissosiates into ions when dissolved in water which is an actual property of a salt.

Hence, The salt would be neutral in this given scenario.
