how to tell soda ash & sodium bicarbonate

[SeeFu]

I think when I was mixeding my soda ash and sodium bicarbonate bottles, i got them mixed up. Is there a way to tell which is which?

Once dissolved I can't think of a way.

pH or alkalinity will tell.

pH is easiest.
Sodium bicarbonate is in the 8's and sodium carbonate is in the 11's.
