Henderson equation for pH Henderson equation for pH[′hen·dər·sən i¦kwā·zhən fər ¦pē′āch] (physical chemistry) An equation for the pH of an acid during its neutralization: pH = pKa + log [salt]/[acid], where pKa is the logarithm to base 10 of the reciprocal of the dissociation constant of the acid; the equation is found to be useful for the pH range 4-10, providing the solutions are not too dilute. |
