1.0 M H_2C_2O_4 के 500 mL, 2.0 M H_2SO_4 के 100 mL और 40 ग्राम NaOH को एक साथ मिलाया जाता है, 30 mL...

500 " mL of " 1.0 M H_2C_2O_4 , 100 " mL of " 2.0 M H_2SO_4 , and 40 g of NaOH are mixed together, 30 " mL of " the above mixture is titrated against a standard solution of sodium carbonate containing 14.3 g of Na_2CO_3.10H_2O per 100 " mL of " solution. Find the volume of carbonate solution used for complete neutralisation.

Calculate the normality of mixture obtained by mixing a. 100 mL of 0.1 N HCl + 50 mL of 0.25 N NaOH b. 100 mL of 0.2 M H_(2) SO_(4) + 200 mL of 0.2 M HCl c. 100 mL of 0.2 M H_(2) SO_(4) + 100 mL of 0.2 M NaOH d. 1g equivalent of NaOH + 100 mL of 0.1 N HCl
