`0.3 g` of an oxalate salts was dissolved in `100 mL` solution. The solution required `90 mL` of `N//20 KMnO_(4)` for complete oxidation. The `%` of oxalate ion in salt is:A. `33%`B. `66%`C. `70%`D. `40%` |
Answer» Correct Answer - B `"Meq. of oxalate" = "Meq. Of" KMnO_(4)` `(w)/(88/2) xx 1000 = 90 xx (1)/(20)` `:. w_("oxalate") = 0.198 g` `% "oxalate " = (0.198)/(0.3) xx 100 = 66%` |
