Chemical equation Question-Dipotassium phosphate

Post by Mike Oldsberg »

I am wanting to re-check my math. I am wishing to prepare a 30% solution of Dipotassium Phosphate (K2HPO4) using 75% Phosphoric acid and (dry) Potassium Carbonate crystals. I would like to re-check my math.

For a 500 gram sample, how much water, 75% phosphoric acid and (dry) potassium carbonate should I add? The water weight percentagelisted on the C of A for the potassium carbonate is listed as <0.06%.

If you can help, tha would be great!
