The correct Answer is:
`A to (r, s), B to (q, t) , C to (p) D to (s, t)`
(A) `Na_(2)CO_(3) + NaHCO_(3)`
Using phenolphthalein indicator .
eq of `Na_(2)CO_(3)` will react.
` :. 1^(st)` titre value
`Na_(2) CO_(3) + HCl to NaHCO_(3)+ NaCl`
` :. 1^(st) ` titre value = eq of `Na_(2)CO_(3)`
Using methyl orange indicator :
eq of `NaHCO_(3) ` produced from `Na_(2)CO_(3)` & eq of `NaHCO_(3)` present will react :
`NaHCO_(3) + HCl to NaCl + H_(2)O + CO_(2)`
` :. 2^(nd) ` titre value = eq of `Na_(2)CO_(3) + " eq of " NaHCO_(3)` .
` A to r, s`
(B) `Na_(2)CO_(3) + NaOH`
