A is a solution of 0.050mol/dm^3 hydrochloric acid.
B is 0.025mol/dm^3 of a trioxocarbonate(IV) solution.
25cm^3 portions of B required an average of 24.6cm^3 of solution of A for complete neutralization, using methyl orange as the indicator.
a) Calculate the number of mole of A in the average titre value.
b) Calculate the number of mole of B in the volume of B pipetted.
c) Calculate the mole ratio of the acid to trioxocarbonate(IV) solution in the reaction, expressing your answer as a whole number ratio of one.
d) State whether the pH of the following would be equal to 7, greater than 7 or less than 7:
i) Solution A
ii) Solution B
iii) Titration mixture of A and B before endpoint.?
