Give chemical reaction of aluminum with dilute $HCl$ ?
Aluminum on dilution with $\mathrm{HCl}$ produces hydrogen gas low concentration. $2 \mathrm{Al}+6 \mathrm{HCl}+12 \mathrm{H}_{2} \mathrm{O} \rightarrow 2\left(\mathrm{Al}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6}\right) \mathrm{Cl}_{3}+3 \mathrm{H}_{2}$

Given below are two statements: one is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A$ : Boric acid is a weak acid
Reason $R$ : Boric acid is not able to release $H ^{+}$ion on its own. It receives $OH ^{-}$ion from water and releases $H ^{+}$ion.
