When an electric current is passed through acidified water, `112ml` of `H_(2)` gas at `NTP` is collected at the cathode is `965` seconds. The current passed in amperes isA. 1B. `0.5`C. `0.1`D. 2 |

Answer» Correct Answer - A 1 g eq. of `H_(2)` , i.e., 1 g or 11200 cc is obtained from 96500 C `therefore` 112 mL will be obtained from 965 C . `I(A) = (Q)/(t) = (965)/(965) = 1A`. |
