- Give the summary of reaction and rationalization of each samples.An impure sample of Na3PO3 weighing 0.1392 g was dissolved in 25 mL of water. A solution containing 50 mL of 3% w/v mercury(II) chloride, 20 mL of 10% w/v sodium acetate, and 5 mL of glacial acetic acid was then prepared. The solution containing the phosphite was added dropwise to the second solution, oxidizing PO3^3– to PO4^3– and precipitating Hg2Cl2. After digesting, filtering, and rinsing, the precipitated Hg2Cl2 was found to weigh 0.4320 g. Report the purity of the original sample as %w/w Na3PO3. Moles Na3PO3 = moles Hg2Cl2I received the following question from the professor. The answer is H2SO4, NaCN for the agent and H2O for the solvent. But some people say the answer is KCN and HCN. 1.
