Vedclass · Answer

(C) $(i)$ $Zn$ is an amphoteric metal. It reacts with both acids and bases to liberate $H_2$ gas: $Zn_{(s)} + 2HCl_{(aq)} \longrightarrow ZnCl_{2(aq)} + H_{2(g)}$ $Zn_{(s)} + 2NaOH_{(aq)} + 2H_2O_{(l)} \longrightarrow Na_2[Zn(OH)_4]_{(aq)} + H_{2(g)}$ Thus,statement $(i)$ is correct. $(ii)$ $Ti$ and $Zr$ are transition metals that form non-stoichiometric interstitial hydrides. Thus,statement $(ii)$ is correct. $(iii)$ The viscosity of $D_2 O$ is higher than that of $H_2 O$ due to stronger hydrogen bonding in $D_2 O$. Thus,statement $(iii)$ is incorrect.

Identify the correct statements from the following.
$(i)$ $Zn$ reacts with dilute $HCl$ and aqueous $NaOH$ solution separately and liberates hydrogen.
$(ii)$ $Ti$ and $Zr$ form interstitial hydrides.
$(iii)$ The viscosity of $H_2 O$ is more than the viscosity of $D_2 O$.
