Question

If 1 stands for true and 0 stands for false, choose the correct code for the following statement:
Concentration of $H_{2} C_{2} O_{4}$ can be determined by $M n O_{4} / H^{+}$ as well as by $N a O H$ .

Solution

Oxalic acid is an acid and reacts with the base, sodium hydroxide.
Hence, the concentration of oxalic acid can be estimated with acid base titration using sodium hydroxide.
Potassium permanganate is a strong oxidizing agent. It oxidises oxalic acid.
Hence, the concentration of oxalic acid can also be estimated by redox titration using potassium permanganate solution.
