Baked Baking soda not dissolved completely

[ZhiYung]

I just baked some Arm and Hammer baking soda at 150C for 1 hour and mixed them into 2 jars of Ro/Di water but they just did not dissolved into the solution. What should I do now ?

I have also tried to stir them for 30 mins, nothing changed.

It might not be ugly baked. Options are to add more water and just use a weaker solution, try boiling it to drive off more CO2, or start over.

The alk solutions are close to the solubility limit.
