A solution of `Ni(NO_(3))_(2)` is electrolyzed between platinum electrodes using a current of 5 amperes for 20 min. What mass of Ni is deposited at the cathode?
(Atomic mass of Ni = 58.7)
[Report your answer by rounding it upto nearset whole number]

Text Solution

Verified by Experts

Quantity of electricity passed=(5A)`xx(20xx60s)=6000C`
`Ni^(2+)+2e^(-)toNi`
Thus, `2F`, i.e., `2xx96500C` deposit Ni=1 mole, i.e., 58.7g
`therefore6000C` will deposit `Ni=(58.7)/(2xx96500)xx6000g=1.825g`.
