Formulation Advice
he pH of sodium citrate depends on its concentration and the presence of other buffering components in a solution. However, as a trisodium salt of citric acid, it typically forms a slightly alkaline solution when dissolved in water.
•A 1% sodium citrate solution has a pH of around 7.5 – 9.0.
•A higher concentration will generally result in a more alkaline pH.
