Barium reacts with water to produce a colourless solution, V.
A sample of V is shaken with MgCl(aq) to produce mixture W. An excess of HCl(aq) is added to mixture W to produce mixture X.
A second sample of V is shaken with MgSO(aq) to produce mixture Y. An excess of HCl(aq) is added to mixture Y to produce mixture Z.
Observations of W, X, Y and Z are made when any reaction is complete.
In which of W, X, Y and Z is a white solid observed?
