Solution :-

  • KBr

KBr + H2\( \leftrightarrow\) KOH (Strong base)+ HBr (Strong acid)Thus, it is a neutral solution.

  • NH4NO3

NH4NO3 + H2O\( \leftrightarrow\) NH4OH(Weak base) + HNO2 (Strong acid)Thus, it is an acidic solution.

  • KF

KF + H2\( \leftrightarrow\) KOH (Strong base) + HF (weak acid)Thus, it is a basic solution.

  • NaNO2

NaNO2 + H2\( \leftrightarrow\) NH4OH(Strong base) + HNO2(Weak acid)Thus, it is a basic solution.

  • NaCN

NaCN + H2\( \leftrightarrow\) HCN (Weak acid) + NaOH (Strong base)Thus, it is a basic solution.

  • NaCl

NaCl + H2\( \leftrightarrow\) NaOH (Strong base) + HCL (Strong acid)Thus, it is a neutral solution.
