The next row, labelled C for "improve", specifies the changes that take place once the acid dissociates. The acid focus decreases by an amount −x, plus the concentrations of the− and H+ both enhance by an quantity +x. This follows within the equilibrium expression. The third row, labelled E for "equilibrium", provides jointly the first two rows and demonstrates the concentrations at equilibrium.
