The flocculation value of HCl for arsenic sulphide sol is 30 m mol L-1...
To find the amount of H2SO4 in grams required for the flocculation of arsenic sulphide, we first need to convert the given flocculation value from m mol L-1 to grams per liter.
The molar mass of HCl is 36.46 g/mol.
30 m mol L-1 * (36.46 g/mol) = 1093.8 g/L
Now, we need to calculate the amount of H2SO4 required in 250 mL (0.25 L) of solution.
Amount of H2SO4 = 0.25 L * 1093.8 g/L = 273.45 grams
Therefore, the amount of H2SO4 in grams required for the flocculation of arsenic sulphide is 273.45 grams.

The flocculation value of HCl for arsenic sulphide sol is 30 m mol L-1...
Arsenic sulphide sol is negatively charged, so H+ brings about precipitation.
For 1 L, 30 m mol of HCl is required.
For 250 ml, 30/4 m mol of HCl is required.
For 250 ml, 30/4 x 2 m mol of H2SO4 is required.
∴ Weight of H2SO4 required = 30/4 x 2 × 10-3 × 98 g
= 0.3675 g
= 3.6 × 10-1 g
≈ 4 × 10-1 g
For 1 L, 30 m mol of HCl is required.
For 250 ml, 30/4 m mol of HCl is required.
For 250 ml, 30/4 x 2 m mol of H2SO4 is required.
∴ Weight of H2SO4 required = 30/4 x 2 × 10-3 × 98 g
= 0.3675 g
= 3.6 × 10-1 g
≈ 4 × 10-1 g
