    (i) NaCl:

    NaCl+H2O↔NaOH+HCl

    Strong base Strong acid

    Therefore, it is a neutral solution.

     

    (ii) KBr:

    KBr+H2O↔KOH+HBr

    Strong base  Strong acid

    Therefore, it is a neutral solution.

     

    (iii) NaCN:

    NaCN+H2O↔HCN+NaOH

    Weak acid  Strong base

    Therefore, it is a basic solution.

     

    (iv) NH4NO3

    NH4NO3+H2O↔NH4OH+HNO3

    Weak base    Strong acid

    Therefore, it is an acidic solution.

     

    (v) NaNO2

    NaNO2+H2O↔NaOH+HNO2

    Strong base    Weak acid

    Therefore, it is a basic solution.

     

    (vi) KF

    KF+H2O↔KOH+HF

    Strong base   Weak acid

    Therefore, it is a basic solution.
