7.63     Predict if the solutions of the following salts are neutral, acidic or basic: $NaCl, KBr,NaCN,NH_{4}NO_{3},NaNO_{2}and KF$

Views

Salts of strong acid and strong base are neutral in nature for example-

• $NaCl (NaOH + HCl)$
• $KBr(KOH+ HBr)$

Salts of a strong base and weak acid are basic in nature for example-

• $NaCN(HCN+NaOH)$
• $NaNO_{2}(HNO_{2}+NaOH)$
• $KF (KOH+HF)$

Salts of strong acid and a weak base are acidic in nature for example-

• $NH_4NO_{3} (NH_4OH+HNO_{2})$
