for K3PO4 is it potassium phophate or tripotassium phosphate? or both? confuse which one we use more often?

Answer 1

Since PO4^- is undeniably phosphate, I think potassium phosphate is ok; however, tripotassium phosphate is not wrong. I know Na3PO4 is commonly called trisodium phosphate.

Answer 2

thanks
