3) A company needs to verify the amount of nitrogen in their new "QuikGreen" fertilizer product. To test the nitrogen content, a 5.01 g sample of fertilizer is dissolved in 100.0 mL of water, and powdered aluminum and sodium hydroxide added. The mixture is left to react and then heated to remove any dissolved NH3 which is transferred to a flask containing 50.0 mL of 0.989 M hydrochloric acid where it undergoes a neutralization reaction. The HCI solution is then titrated to methyl red endpoint using 11.74 mL of 0.251 M sodium hydroxide. a) How many grams of nitrate were in the original sample?

Tungsten trioxide (WO,) has a rich yellow color and is often used as a pigment in ceramics and paints. To test a ceramic vase for its WO, content, a 10.15 g sample of the vase was ground and reduced with Pb(Hg) to convert any WO, to W³+. The resulting W3+ was transferred to 500.0 mL of 1.00 M HCI. A 100.00 mL aliquot of the HCl solution required 14.78 mL of 0.08271 M potassium permanganate (KMNO,) to reach the purple endpoint. A blank required 0.26 mL. Balance the redox reaction. redox reaction: MnO, + W3+ Mn2+ + WO3+ Determine the percent WO, in the ceramic sample. percent WO3: %
