Abstract A complete mathematical account of the buffer capacity of bivalent ampholytes is given. The consistent use of dimensionless parameters makes it possible to obtain very neat expressions and equations. Direct proof of the well‐known condition K 1 ⩾ 4 K 2 is presented. Since water is also an ampholyte, its buffer capacity is considered as well.
