- show solutions pls. thanksAn impure sample of Na3PO3 weighing 0.1 g is dissolved in 35 mL of water. A solution containing 45 mL of 3% w/v HgCl2, 30 mL of 10% w/v sodium acetate, and 10 mL of glacial acetic acid is then prepared. After digesting, filtering, and rinsing the precipitate, 0.2857 g of Hg2Cl2 is obtained. Report the purity of the original sample as % w/w Na3PO3.100 g of soil is leached with a strong solution of Calcium chloride such that all the exchange sites are occupied by Ca2+. The soil is subsequently leached again with a strong solution of magnesium chloride. It is determined that the resulting 100 mL leachate contains 5000 mg of Ca2+. What is the soil CEC (cmolc/kg)? The atomic wt. of Ca is 40 g/mol.please answer in word don't image upload thank you.
