1. Solve the following queries related to gravimetric analysis. Make sure to show full and complete procedure. a) A sample of pure KCIOx weighing 0.28 g is reduced to KCI and then precipitated with silver nitrate, giving 0.29 g of AgCl. What is the value of x in the original formula? In her PhD research, Marie Curie measured the atomic mass of radium she had discovered. From its chemical properties, he knew that Radium is in the same family b) as Barium, so the formula for radium chloride is RaCl₂. When 0.09192 g of pure RaCl₂ was dissolved and treated with an excess of silver nitrate, 0.08890 g of AgCl were precipitated. Find the atomic mass of Ra. c) A 7.0 g sample of a pesticide was broken down with metallic sodium into alcohol and the released chloride ion was precipitated as AgCl. Express the results of this analysis in terms of the percentage of DDT (C14H9Cl5) based on a recovery of 0.2513 g of AgCl.
