This is the amount that represents the change in pH of a solution when base B is added to a buffer solution. Here, the unit of concentration of B is defined as HO - mol L -1 . It represents the amount of base required to change the unit pH, and the greater the buffer capacity, the smaller the change in pH when base B is added, indicating that it is an excellent buffer solution.
