A is \( 0.100 \mathrm{~mol} \mathrm{dm}^{-3} \) of HCl. B is \( 0.030 \mathrm{mol} \mathrm{dm}^{-3} \) of a trioxocarbonate (IV) salt.

Question Parts

( a )

Put A into the burette and titrate it with \( 20.0 \mathrm{~cm}^{3} \) or \( 25.0 \mathrm{~cm}^{3} \) portion of B using methyl orange as indicator. Repeat the titration to obtain concordant titre values. Tabulate your results and calculate the average volume of A used.

( b )

From your results and the information provided, calculate the mole ratio of the acid to the trioxocarbonate (IV) in the reaction.

( c )

Given that \( B \) contains \( 5.0 \mathrm{~g} \mathrm{dm}^{-3} \) of the hydrated trioxocarbonate (IV) salt, calculate the:
