Fourth, it has excellent solubility. The solubility of sodium citrate is excellent and becomes better when the temperature becomes higher.
Fifth, it is with good PH adjustment ability and cushion performance. Sodium citrate is a kind of weak acid and strong alkali salt. Together with citric acid, they can make a strong PH buffer agent.
