Question

100 mL solution containing 0.1 mol each of K 2 ​ CO 3 ​ and KHCO 3 ​ is titrated with 0.1 M acid using either phenolphthalein or methyl orange indicater. Select the correct horizontal match :

TestHub · Accepted Answer

HPh : CO 3 ​ 2 − + H + → HCO 3 ​ − MeOH : CO 3 ​ 2 − + 2 H + → H 2 ​ CO 3 ​ HCO 3 − ​ + H + → H 2 ​ CO 3 ​ In presence of HPh 10 m mole of K 2 ​ CO 3 ​ is neutralized by 10 m mol of an acid i.e., 100 mL 0.1 M HCl .
