Monocalcium phosphate - Wikipedia
Calcium dihydrogen phosphate is used in the food industry as a leavening agent, i.e., to cause baked goods to rise. Because it is acidic, when coined with an alkali ingredient, commonly sodium bicarbonate (baking soda) or potassium bicarbonate , it reacts to produce carbon dioxide and a salt .
Demonstrations - Calcium + Water
After a second or so, the calcium metal begins to bubble vigorously as it reacts with the water, producing hydrogen gas, and a cloudy white precipitate of calcium hydroxide. The presence of the hydroxide is demonstrated by the addition of a few drops of phenolphthalein indior, which turns the solution pink, indiing that the solution is basic.

Phosphoric acid - WikiMili, The Best Wikipedia Reader
Phosphoric acid, H 3 PO 4, is a tribasic acid.The speciation diagram shows that, in aqueous solution, there are five main pH regions. There are 3 regions, centred where the pH is equal to a pK value, which are buffer regions.In the region centred around pH 4.7 (mid-way between the first two pK values) the dihydrogen phosphate ion, [H 2 PO 4] −, is the only species present.
