In iodometric estimation of Cu2+ ions, the following reactions take place

If 100mL of CuSO4 solution added to an excess of KI requires 50mL of 0.2 M Na2S2O3, the molarity of CuSO4 solution is


0.66 g H3PO2 will require x mL of 0.1 NaOH for complete neutralization .x is


20mL solution containing 0.1 M each of HCl and HNO3 required mL of 0.1 M NaOH for complete neutralization. In another experiment to 20mL of original solution, excess of AgNO3 is added and the precipitate of AgCl is filtered off. The entire filtrate along with washings required y mL of the same NaOH solution for neturalization. Then, which of the following relation is correct?
