Which of the following gives equivalent mass of `Na_(2)CO_(3)` when titrated against HCl in the presence of methyl orange ?

A

5.3

B

53

C

10.6

D

106

Text Solution

Verified by Experts

The correct Answer is:
B
`Na_(2)CO_(3)+2HCl overset("Methyl orange")to 2NaCl+H_(2)O+CO_(2)`
Equivalent mass=molecular `"mass"//2=106//2=53`

Which of the following on boiling with Na_(2)CO_(3) (aq) gives aniline ?

If amixture of Na_(2)CO_(3) and NaOH in equimolar quantities when reacts with 0.1 M HCl in presence of phenolphthalein indicator consumes 30 ml of the acid. What will be the volume (in mL) of 0.15 M H_(2)SO_(4) used in the separate titration of same mixture in presence of methyl orange indicator.

During the titration of a mixture of Na_(2)CO_(3) and NaHCO_(3) against HCl :

In the study of titration of NaOH and Na_(2)CO_(3) . NaOH and NaHCO_(3) , Na_(2)CO_(3) and NaHCO_(3) , phenophthalein and methyl orange are used as indicators. (a). When phenolphthalein is used as an indicator for the above mixture: (i). It indicates complete neutralisation of NaOH or KOH (ii). It indicates half neutralisation of Na_(2)CO_(3) because NaHCO_(3) is formed at the end point. (b). When methyl orange is used as an indicator for the above mixture (i). It indicates complete neutralisation of NaOH or KOH (ii). It indicates half neutralisation of Na_(2)CO_(3) because NaCl is formed at the end point. Q. 1 L solution of Na_(2)CO_(3) and NaOH was made in H_(2)O . 100 " mL of " this solution required 20 " mL of " 0.4 M HCl in the presence of phenolphthalein however, another 100 mL sample of the same solution required 25 " mL of " the same acid in the presence of methyl orange as indicator. What is the molar ratio of Na_(2)CO_(3) and NaOH in the original mixture.
