Group 2 — practice question

A reaction sequence for a Group $2$ metal, M, is shown. $\text{M} \xrightarrow[]{\text{reacts with oxygen}} \text{X} \xrightarrow[]{\text{reacts with water}} \text{Y} \xrightarrow[]{\text{reacts with sulfuric acid}} \text{Z}$ Which row is right as M moves down Group $2$ from Mg to Ba?

  • Asolubility of Y in water decreases; solubility of Z in water decreases
  • Bsolubility of Y in water decreases; solubility of Z in water increases
  • Csolubility of Y in water increases; solubility of Z in water decreases
  • Dsolubility of Y in water increases; solubility of Z in water increases
