`25 mL` of a solution of barium hydroxide on titration with `0.1 "molar"` solution of hydrochloric acid give a titre value of `35 mL`. The molarity of barium hydroxide is:A. `0.28`B. `0.35`C. `0.07`D. `0.14` |

Answer» Correct Answer - C Meq.of `Ba(OH)_(2)="Meq.of" HCl` `Nxx25=0.1xx35` `therefore N_(Ba(OH)_(2))=(3.5)/(25)` `therefore M_(Ba(OH)_(2))=(3.5)/(25)xx(1)/(2)=0.07` |
