Question

Equations relating to acidic properties of an aq. solution of HCl gas is/are :

• A. $HCl\left(g\right)+H_{2}O\rightleftharpoons H_3{O}^{+}+{Cl}^{-}$
• B. $Zn{\left(OH\right)}_2+2HCl\to {ZnCl}_2+2H_{2}O$
• C. ${MnO}_2+4HCl\to {MnCl}_2+{Cl}_2+2H_{2}O$
• D. all of the above

Answer 1

The correct option is D all of the above

1) $HCl\left(g\right)+H_{2}O\rightleftharpoons H_3{O}^{+}+{Cl}^{-}$
2) ${2KMnO}_4+16HCl\to {2MnCl}_2+{8H}_{2}O+2KCl+{5Cl}_2$
3) ${MnO}_2+4HCl\to {MnCl}_2+{Cl}_2+2H_{2}O$
4) $Zn{\left(OH\right)}_2+HCl\to {ZnCl}_2+H_{2}O$

All of the above equation shows the acidic properties of hydrochloric acid.
