Question

observing the action of zn, fe, cu, or al metals on the following salt solution question no (1) znso4 (aq)​

Answer 1

Answer:

In electrochemical series, the elements with more negative SRP are considered as more reactive.

So, order will be Al>Zn>Fe>Cu.

But, when the aqueous soltions of salts of alkali metals, alkaline earth metals, Al, Zn,Fe, Ni etc, are electrolysed by using inert electrodes, at cathode instead of those metals, H+ ions undergo reduction and produce H2 gas.
