The pH of disodium hydrogen phosphate water solution is between 8,0 and 11,0, meaning it is moderately basic: HPO 4 2− + H 2 O ⇌ H 2 PO 4 − + OH − Contents

Disodium phosphate

 · I am using the disodium version of EDTA that is the only one available in my lab right now and the molecular weight is 372,24g/mol, I tried to make a 1M stock by dissolving 186,1g of EDTA in 500mL of water, but it REFUSES to dissolve, I went on to check that it is necessary to change the pH of the solution to 8,0 before the powder will go into the solution, but still, it DOESNT dissolve,
