If \(1\, A\) of current is passed through \(CuS{O_4}\) solution for \(10\) seconds, then the number of copper ions deposited at the cathode will be about
1 \(1.6 \times {10^{19}}\)
2 \(3.1 \times {10^{19}}\)
3 \(4.8 \times {10^{19}}\)
4 \(6.2 \times {10^{19}}\)
Explanation:
(b) Total charge supplied \( = 1 \times 10 = 10\,C\) \(2\) electronic charge \((3.2 \times {10^{ - 19}}C)\) liberates one \(C{u^{ + 2 }}\) ion Number of \(C{u^{ + 2 }}\) ions liberated by \(10\, C\) charge \( = \frac{1}{{3.2 \times {{10}^{ - 19}}}} \times 10\)\( = 3.1 \times {10^{19}}\)
