\mathrm{pH}=2

and vessel

B

contains

100 \mathrm{~mL}

\mathrm{NaOH}

\mathrm{pH}=12 . \mathrm{Al}_2 \mathrm{O}_3

is added in each vessel. Molar ratio of

\mathrm{Al}_2 \mathrm{O}_3 ~1.8 \mathrm{gmL}^{-1}

required by

A

and

B

View answer and explanation

Correct option: C

0.04375

Option C (0.04375) is correct because it represents the molar ratio of

Al_2O_3

required by A and B, calculated by considering the moles of HCl and NaOH neutralized by

Al_2O_3
