Q. The metal that products $H_2$ with both dil $HCl$ and $NaOH (aq)$ is

KCETKCET 2020Hydrogen

Solution:

$Zn$ produces $H _{2}$ with both dil. $HCl$ and $NaOH ( aq )$. The corresponding reactions are:

$Zn +2 HCl \rightarrow ZnCl _{2}+ H _{2} \uparrow$

$Zn +2 NaOH \rightarrow Na _{2} ZnO _{2}+ H _{2} \uparrow$
