Number of moles of \(\mathrm{K}_2 \mathrm{Cr}_2 \mathrm{O}_7\) required to oxidise one mole of sodium oxalate completely in acid medium will be : [RBQ]
163259
Choose the correct statement(s) from the following: [RBQ]
1 Cathode and anode are negative terminal in electrolytic and galvanic cell
2 Cathode is negative terminal in both electrolytic \& galvanic cell
3 Anode is positive terminal in both electrolytic and galvanic cell
4 All of these
Explanation:
The aim of two cells is opposite. In electrolytic cell, cation (+vely charged) moves towards cathode (vely charged) while in galvanic cell electron goes away from anode and are attracted towards cathode.
