How many electrons are delivered to the cathode during electrolysis by a current of 1 ampere in 193 seconds?

Answer:

Solution:

Charge = Current(amp) $\times$ Time(sec) = $1 \times 193 = 193$ C.

Number of faradays = $\frac{193}{96500} = \frac{1}{500}$ .

$1$ F charge = $6.023 \times 1 0^{23}$ electrons.

$\frac{1}{500}$ F charge = $6.023 \times 1 0^{23} \times \frac{1}{500} = 1.2 \times 1 0^{21}$ .
