Question

$C a (H C O_{3})_{2}$ is determined volumetrically by titration with acid. The indicators are:
(a) Phenolphthalein
(b) Methyl red
Out of this two indicators, methyl red is better suited here.
If true enter 1, else enter 0.

Solution

Methyl red is only used. Phenolphthalein does not indicate any colour change. Hence, $C a (H C O_{3})_{2}$ is determined volumetrically by titration with acid using methyl red indicator.
Hence, the statement is true.
