Calculation in the pH with a polyprotic acid needs a speciation calculation for being performed. In the situation of citric acid, this involves the solution of The 2 equations of mass equilibrium:
Shampoos: Buffers like citric acid and sodium hydroxide are used in shampoos to balance out the alkalinity that would normally burn up our scalp. These buffers counteract the alkalinity with the detergents present during the shampoo.
