`20 mL` of a solution containing equal moles of `Na_(@)CO_(3)` and `NaHCO_(3)` required `16 mL` of `0.16 M HCl` solution to reach the phenolphthalein end point. What volume of a `0.10 M H_(2)SO_(4)` solution would have been required had methyl orange been used as indicator?

0.1g of a solution containing Na_(2)CO_(3) and NaHCO_(3) requires 10mL of 0.01 N HCl for neutralization using phenolphthalein as an indicator, mass% of Na_(2)CO_(3) in solution is:

40 mL 0.05 M solution of sodium sesquicarbonate dehydrate (Na_(2)CO_(3).NaHCO_(3).2H_(2)O) is titrated against 0.05 M HCl solution, x mL of acid is required to reach the phenolphthalein end point while mL of same acid were required when methyl organe indicator was used in a separate titration. Which of the following is (are) correct statements? a. y-x = 80 mL b. y+x = 160 mL c. If the titration is started with phenolphthalein indicator and methyl orange is added at the end point, 2 x mL of HCl would be required further to reach the end point d. If the same volume of same solution is titrated against 0.10 M NaOH, x//2 mL of base would be required
