Assertion(A) : In electrolysis, the quantity of electricity needed for depositing 1 mole of silver is different from that required for 1 mole of copperReason (R): The molecular weights of silver and copper are different
On electrolysis, 1 mole of aluminium will be deposited from its molten salt by
Chromium metal can be plated out from an acidic solution containing $Cr{{O}_{3}}$ according to the following equation (atomic weight of $Cr = 52$). $Cr{{O}_{3}}(g)+6{{H}^{+}}+6e\to Cr(s)+3{{H}_{2}}O$, How many grams of chromium will be plated by 22400 C
A quantity of 0.300 g of $Cu$ was deposited from a $CuS{{O}_{4}}$solution by passing a current of 3.00 A through it for 304 s. The value of the Faraday constant is
Assume that during electrolysis of $AgNO_3$, only $H_2O$ is electrolysed and $O_2$ is formed as, $2{{H}_{2}}O\to 4{{H}^{+}}+{{O}_{2}}+4{{e}^{-}}$, $O_2$ formed at NTP due to passage of 2 Amperes of current for $965 s$ is
Calculate the volume of gas liberated at the anode at STP during the electrolysis of a $CuS{{O}_{4}}$ solution by a current of 1 A passed for 16 minutes 5 seconds
After the electrolysis a sodium chloride solution with inert electrodes for a certain period of time, 600 mL of a 1 N $NaOH$ solution was left. During the same time 31.80 g $Cu$ was deposited in a copper voltameter in series with the electrolytic cell. Calculate the percentage of $NaOH$ obtained (atomic weight of $Cu = 63.6$)
$1 g$ equivalent of $Na$ metal is formed from electrolysis of fused $NaCl$. Number of mol of $Al$ from fused $N{{a}_{3}}Al{{F}_{6}}$ will be same current
Which is responsible for electrical conduction of molten sodium chloride
Pure water does not conduct electricity because it
