The 2nd row, labelled C for "alter", specifies the alterations that take place if the acid dissociates. The acid focus decreases by an total −x, plus the concentrations of the− and H+ both equally boost by an volume +x. This follows through the equilibrium expression. The 3rd row, labelled E for "equilibrium", adds jointly the primary two rows and reveals the concentrations at equilibrium.
