$B(OH)_3$ does not donate a proton and therefore does not form a salt with $NaOH$.

Vedclass · Answer

(C) $B(OH)_3$ (Boric acid) is a weak monobasic Lewis acid,not a strong acid.It acts as a Lewis acid by accepting an $OH^-$ ion from water: $B(OH)_3 + 2H_2O \rightleftharpoons [B(OH)_4]^- + H_3O^+$.It does not donate a proton $(H^+)$ directly,but it reacts with $NaOH$ to form sodium metaborate or sodium tetrahydroxoborate: $B(OH)_3 + NaOH \rightarrow Na[B(OH)_4]$.Therefore,the statement that it does not form a salt with $NaOH$ is incorrect.
