Hello,

I'm trying to prepare 20% sodium bicarbonate solution, and I'm having trouble getting it to dissolve. I placed 10g in 50 mL DI water, and the solution is just very cloudy. Since I can't heat it, is there another way to dissolve it? I plan on filter sterilzing it afterwards.

Thanks!

see the solubility chart of this compound:


Solubility in water 9 g/100 mL
69 g/L (0 °C)^[2]
96 g/L (20 °C)^[3]
165 g/L (60 °C)^[3]
236 g/L (100 °C)^[2]

So heating will help..
but since you cant do this.. no other option then diluting it.
