Define Reagents Estimation of Iron in the Solution?

1. Conc. sulphuric acid (iron free)

2. Conc. potassium permanganate solution

3. Saturated potassium persulphate (K2S2O3) solution:

Shake 7-8 g of reagent grade iron free potassium persulphate with 100 ml of water in a glass stoppered bottle. Compensate for loss by decomposition. Shake briefly before use. Keep the reagent in the refrigerator.

4. 3N potassium thiocyanate solution:

Dissolve 146 g of potassium thiocyanate in 480 ml ofdistilled water. Filter ifturbid. Add 20 ml of acetone to improve keeping quality.
