In order to gain a better understanding of the setting of the monocalcium phosphate monohydrate–calcium oxide cement that we developed and in the aim to improve its mechanical properties, the setting reaction was studied by pH-metry. It may make the pH of a potting mix far too alkaline for safe use on orchids. Update: I got answer but actually it wasn't properly balanced. Journal of Endodontics. This is due to Calcium being oxidation state +2 and Oxygen oxidation state is -2, this means when formed in a compound they cancel each other out to give CaO. A clear solution of the hydroxide in water is known as lime water. In the hydrogen wasn't properly balanced. By slaking the paste formed from the oxide with an excess of water, a suspension called "milk of lime" is formed.
