Vedclass · Answer

(A) The chloride of an element $A$ forms a neutral solution in water if it is a salt of a strong acid and a strong base. Elements of the $1^{st}$ group (alkali metals) form chlorides like $NaCl$ or $KCl$,which are salts of a strong base $(NaOH/KOH)$ and a strong acid $(HCl)$. These salts do not undergo hydrolysis,resulting in a neutral solution with $pH = 7$. Therefore,the element $A$ belongs to the $1^{st}$ group.
