WebJul 1, 1971 · Hemolytic behavior of human erythrocytes in sodium and potassium phosphate buffer systems was investigated. The data were used to calculate hemolytic i values for the buffer components at various pH values. The experimental i values were lower than those predicted by a theoretical equation, and the deviations were attributed to changes in pH … WebOct 22, 2024 · Buffer pH. The ideal pH or pOH for a buffer to work at is the pK value of the acid or base that makes the buffer. Lets consider an acid and its salt, but realize we could apply this to a base and its salt. When the concentration of the acid equals the salt, the buffer can neutralize equal amounts of an external acid or base.
