WebJan 1, 2024 · A buffer is a solution containing substances which have the ability to minimise changes in pH when an acid or base is added to it 1. A buffer typically consists of a solution which contains a weak acid HA mixed with the salt of that acid & a strong base e.g. NaA. The principle is that the salt provides a reservoir of A - to replenish [A -] when ... WebThere are several ways a solution containing these two components can be made: Buffers can be made from weak acids or base and their salts. Buffers can be made from two salts that provide a conjugate acid-base pair. A buffer can be made by dissolving 15.0 grams NaH 2 PO 4 and 17.7 grams Na 2 HPO 4 in water and diluting to 1.00 liter.
