Calculate the equivalent mass of `Na_(2)CO_(3)` when it is titrated against HCl in presence of phenolphthalein.

What is the equivalent mass of Na_2CO_3 ?

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

(A ) : When Na_(2)CO_(3) is titrated against HCl in presence of phenolphthalein indicator, it is converted into NaCl. (R ) : Phenolphthalein indicator shows colour change in the P^(H) range of 3.5 to 4.6

Calculate the molecular mass of the followings: Na_(2)CO_(3)

When Na_(2)CO_(3) solution is titrated against HCl solution, the indicator used is

A mixture contains 1.0 mole each of NaOH, Na2CO3 and NaHCO3. When half of mixture is titrated with HCI.it required x mole of HCI in presence of phenolphthalein. In another experiment, half of mixture required y mole of same HCI in presence of methyl orange. Find the value of(x + y)
