Britton-Robinson buffer
It consists of a mixture of 0.04 M H[SUB]3[/SUB]BO[SUB]3[/SUB], 0.04 M H[SUB]3[/SUB]PO[SUB]4[/SUB] and 0.04 M CH[SUB]3[/SUB]COOH that has been titrated to the desired pH with 0.2 M NaOH. Britton and Robinson also proposed a second formulation that gave an essentially linear pH response to added alkali from pH 2.5 to pH 9.2 (and buffers to pH 12). This mixture consists of 0.0286 M citric acid, 0.0286 M KH[SUB]2[/SUB]PO[SUB]4[/SUB], 0.0286 M H[SUB]3[/SUB]BO[SUB]3[/SUB], 0.0286 M veronal and 0.0286 M HCl titrated with 0.2 M NaOH.
