Question- Tungsten trioxide (WO3) has a rich yellow color and is often used as a pigment in ceramics and paints. In order to test a ceramic vase for its WO3 content, a 10.17 g sample of the vase was ground and reduced with Pb(Hg) to convert any WO3 to W3 . The resulting W3 was transferred to 500.0 mL of 1.00 M HCl. A 100.00 mL aliquot of the HCl solution required 13.29 mL of 0.08146 M potassium permanganate (KMnO4) to reach the purple endpoint. A blank required 0.28 mL. Balance the reaction below and determine the percent WO3 in the ceramic sample.
