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?
A. hydrogen chloride gas was released in the reactions in both titrations B. the titer values obtained from the titration are equal C. the tirer value obtained by X is twice that of Y D. the titer value obtained by Y is twice that of X
