Magnesium and phosphorus are each reacted on their own with an excess of oxygen to produce their oxides. Each oxide is then added separately to water, and the pH values of the solutions formed are measured. The same two elements are each reacted on their own with an excess of chlorine to produce their chlorides. Each chloride is then added separately to water, and the pH values of the solutions formed are measured. Which row is correct?
- Aoxide giving the higher pH: magnesium; chloride giving the higher pH: magnesium
- Boxide giving the higher pH: magnesium; chloride giving the higher pH: phosphorus
- Coxide giving the higher pH: phosphorus; chloride giving the higher pH: magnesium
- Doxide giving the higher pH: phosphorus; chloride giving the higher pH: phosphorus
