The same volumes of saturated solutions of magnesium hydroxide, calcium hydroxide and strontium hydroxide are fully neutralised by dilute sulfuric acid. The water is then carefully evaporated from each solution formed, so that the matching solid sulfates are left behind. These solid sulfates are next dissolved completely in the smallest amount of water needed to make saturated solutions. Which statement about the volumes of water required to dissolve the sulfates is correct?
- AThe calcium sulfate will require the greatest volume of water.
- BThe magnesium sulfate will require the greatest volume of water.
- CThe strontium sulfate will require the greatest volume of water.
- DThey will all require the same volume of water.
