Buffer capacity depends on two quantities. what are they? view available hint(s) buffer capacity depends on two quantities. what are they? how close the buffer is to having a 10: 1 ratio of the buffer components, and having a high concentration of the components a high concentration of conjugate acid in solution and the ph of the solution the range of ph values over which the solution can act as a buffer and an equal ratio of conjugate acid to conjugate base the proportion of conjugate acid and base and the absolute concentration of each
