A chemist is studying the prоperties оf bоth CаSO4 аnd PbSO4. They аre both white powders. Neither conducts electricity. 1. Describe the structure of the solids that account for their inability to conduct electricity; 2. The chemist places excess CaSO4(s) in a beaker with 100 mL of water. She also adds excess PbSO4 in another beaker containing 100 mL of water. After stirring, she checks the electrical conductivity and determines that it is higher in the CaSO4 beaker. Which compound is more soluble in water - CaSO4 or PbSO4? Justify your answer; 3. View the diagram below. Describe in detail what the PbSO4 beaker would look like in comparison to the CaSO4 beaker; 4. The chemist then tries to increase the solubility of CaSO4 by adding 20.0 mL of 1.0 M H2SO4 to the beaker and observes additional precipitate. Explain.
