Vedclass · Answer

(B) When a mineral acid (such as $HCl$) is added to an aqueous solution of borax $(Na_{2}B_{4}O_{7} \cdot 10H_{2}O)$,it reacts to form orthoboric acid $(H_{3}BO_{3})$.The chemical equation for the reaction is:$Na_{2}B_{4}O_{7} + 2HCl + 5H_{2}O \rightarrow 2NaCl + 4H_{3}BO_{3}$Thus,orthoboric acid is the product formed.Hence,the correct answer is option $B$.
