The calcium oxide reacts with water to form calcium hydroxide, which is much more water-soluble. The sample in Table 1 containing 0.2% calcium carbonate was baked for one hour at 1,000°C. We reran the pH on this sample and it increased to 11.8 while the ADV changed only slightly.
When reacted with water, a metal hydroxide and hydrogen are produced. Place in order of reactivity: potassium, sodium, calcium, magnesium, zinc, iron, (hydrogen) and copper, by reference to the reactions, if any, of the metals with:
