Chemistry - Salt Analysis Question with Solution | TestHub

The vapours of trialkyl borates $\mathrm{B}(\mathrm{OR}{)}_3$ or $R_3{\mathrm{BO}}_3$ burn with green edged flame. This is the qualitative test of borates. $$\begin{array}{r}2{\mathrm{BO}}_3{}^{3-}+3{\mathrm{H}}_2{\mathrm{SO}}_4\to 3{\mathrm{SO}}_4{}^{2-}+{\mathrm{H}}_3{\mathrm{BO}}_3\\ \text{ boric acid }\\ {\mathrm{H}}_3{\mathrm{BO}}_3+3\mathrm{ROH}\to R_3{\mathrm{BO}}_3+3{\mathrm{H}}_2\mathrm{O}\end{array}$$
