Which part is not clear?

What exactly did you use?

There is appears to be milky clouds in ot that hang suspended. I did the baking method, should I heat the solution more to further dissolve it.

You used Arm and Hammer baking soda?

Maybe you did not bake it enough, but warming the solution will help it dissolve.

No I used a non food grade sodium bicarbonate

I also baked it at 250c not 300f, it was slightly brown on the surface so I don't know if this we effect it? The resulting liquid does have a brown tinge and still is a bit frothy so could even be impurities in the sodium bicarb?

Might be impure. Might just not be baked enough. You could try boiling it.

Okay thanks for the follow ups. All the best

I've baked a lot of sodium bicarb in my day....some for tanks, and lately for my uncle's inground pool while h';s in the hospital and I'm taking care of it. Sodium carbonate also does the trick for pools to get pH and alk up, except you use pounds of it, and you bake it the same way.

I've never seen food grade baking soda turn brown when baked. This has to be a contaminate or perhaps anti coagulant agent. Beg to differ with Randy, but is it really worth risking?

I didn't risk it in the end.
