So you have 0.25 molar Na3PO4. But for every one molecule of Sodium phosphate, you have 3 molecules of sodium. Therefore you have 0.25*3 or 0.75 molar sodium.
Let us find moles first. Molarity = moles of solute/Liters of solution ( 750 ml = 0.750 Liters ) 0.375 M Na2SO4 = moles Na2SO4/0.750 Liters = 0.28125 moles Na2SO4 =================== 0.28125 moles Na2SO4 (142.05 grams/1 mole Na2SO4) = 39.95 grams Na2SO4 needed ---------------------------------------you do significant figures!
Na3PO4
When a solution has more hydrogen ions it will be acidic.
0.17 Molar
That you have an acidic solution.

Na3PO4
When a solution has more hydrogen ions it will be acidic.
A Neutral solution
If a solution containing A+ ions and a solution containing B- ions have just been mixed and [A+][B-] is greater thanKsp of AB, _____.
0.17 Molar
Acids will give H+ ions.
nah man. them acids has them lot. the H+ ions that is. but these basic solutions donate a massif amount of OH- ions compared to H+ ions when added to an aqueous solution.
It accepts H+ ions.
acidic
Elevated protons (H+ ions) increase the relative acidity of any solution.
