Sodium Citrate: Citric Acid Neutralised with Soda
Sodium citrate is citric acid with its acid taken up by soda. US Dispensatory (1907): to a hot solution of 59 parts of citric acid add a solution of 53 parts of monohydrated sodium carbonate, neutralise, evaporate and crystallise. With dry soda ash that is 45 parts.
