the oxidation number on the phosphorus in Na3PO4
1. What is the oxidation number phosphorus in H2P04-? 2. Balance the following chemical equation Ti*? + In3+ T1+3 +_ In
How would I find the percent of P2O5 present in a sample of KH2PO4? I know that phosphorus is 22.761% by mass of KH2PO4. I weighed out 0.422g of KH2PO4, then filtered it with water. Then I added 10 mL of 0.4 M MgSO4 to the filtrate. Then I added 1 mL of 6 M NH3 slowly with a disposable pipet while stirring. Then I touched the stirring rod to red litmus paper. Then I continued adding 1 mL NH3...

8) A buffer solution is formed by adding 0.0100 moles of potassium dihydrogen phosphate (KH2PO4) and 0.0100 moles of potassium hydrogen phosphate (K2HPO4) into 1.000 liters of water. When 0.0010 moles of NaOH is added to this solution, what will happen? The pH of the solution will decrease by a large amount ( > 0.10 pH units) The pH of the solution will decrease by a small amount (< 0.10 pH units) The pH of the solution will be exactly...
