Deduce the normality equation, \( N_1V_1 = N_2V_2 \). Experimental data obtained by titrating decinormal solution of oxalic acid with potassium permanganate solution are given below.
| Expt. No. | Volume of oxalic acid (ml) | Volume of KMnO4 burrete reading (ml) | |
| initial | final | ||
| 1 | 10 | 0.0 | 11.5 |
| 2 | 10 | 0.0 | 11.0 |
| 3 | 10 | 0.0 | 11.0 |
a) Name the above titration.
b) Calculate the equivalent weight of\( \text{KMnO}_4 \)
c) Calculate the normality of \( \text{KMnO}_4 \) from the above data.
d) Why is \( \text{dil. H}_2\text{SO}_4 \) added to the conical flask containing standard oxalic acid before titrating with \( \text{KMnO}_4 \) solution ?
e) Identify the titrant and titrand in this titration.
