Experiment 1. Determination of sulfate ions in potassium sulfate Precipitate sulfate ions of potassium sulfate as barium sulfate, filter it, burn it in a crucible, and find the weight by gravimetric analysis. 0.3951 g of K2SO, was weighed precisely, 2 mL of HCI (1+1) was added, and then it was dissolved completely by heating. A 1% BaCl2 solution was added slowly, and whether BaSO4 precipitated or not was checked. (1) Calculate the minimum amount (mL) of the 1% BaCl2 solution required to allow BaSO4 to completely precipitate. Suppose that the concentration of the BaCl2 solution is 1 wt/vol %.
