Student X titrated 25 cm\(^{3}\) of Na\(_{2}\)CO\(^{3}\) with 0.1 mol dm\(^{-3}\) HCI, using methyl orange as indicator. Student Y carried out the same exercise but used phenolphthalein as an indicator. Which of the following statements about the titration is true?
- hydrogen chloride gas was released in the reactions in both titrations
-
the titer values obtained from the titration are equal
- the tirer value obtained by X is twice that of Y
- the titer value obtained by Y is twice that of X
