Potassium sodium tartrate

Raw materials

1. Sodium carbonate

2. Potassium bitartrate

Process

1. Potassium sodium tartrate, (NaKC₄H₄O₆) may be prepared by adding 0.5 mole sodium carbonate to heated solution containing 1 mole potassium bitartrate (KHC₄H₄O₆). (1M KHC₄H₄O₆ : 0.5M Na₂CO₃). 

2. The solution is filtered while hot. 

3. This solution is then dried to precipitate solid potassium sodium tartrate, as small crystallites.
