Where can I find the saturation curve for Na2CO3 (Sodium Carbonate) versus temperature? Thanks, ECD40

Wikipedia has a table in the article on sodium carbonate. You could plot the numbers or Google it. I got a neat curve (attached below)but you have to do a little figuring to get the temperatures. Or you could Google images for sodium carbonate solubility to get other curves.

Washing soda is the decahydrate; soda ash is anhydrous.

Decahydrate: 7 g/100 mL (0 °C) 16.4 g/100 mL (15 °C) 34.07 g/100 mL (27.8 °C)

Heptahydrate: 48.69 g/100 mL (34.8 °C)

Monohydrate: 50.31 g/100 mL (29.9 °C) 48.1 g/100 mL (41.9 °C) 45.62 g/100 mL (60 °C) 43.6 g/100 mL (100 °C)
