I have a formula that uses potassium carbonate. Can I use sodium carbonate
instead? The purpose of the salt in that formula is mainly to set pH. How can
I calculate the amount needed?

I know I can calculate the conversion with molecular weight, but will that
give me the same pH? How can one calculate the conversion to maintain the
same pH?

Thanks in advance!
