Three solutions eaach of 100 mL containing 0.4 M As_(2)S_(3),5M NaOH and 6MH_(2)O_(2), respectively were mixed to form AsO_(4)^(3-) and SO_(4)^(2-) as products. Q. Percentage strength of the H_(2)O_(2) solution left after reaction is |
|
Answer» `0.017%` `N of H_(2)O_(2)` left`=(2XX2)/(15)=(4)/(15)N` `1N of H_(2)O_(2)=(1eq)/(L)H_(2)O_(2)=5.6V` (Volume STRENGTH)`=1.7%` `(4)/(15)NH_(2)O_(2)=1.7xx(4)/(15)=0.452%` |
