Question

When an ionic compound dissolves in water, the cations and anions are separated. Ions in solution will result in that solution conducting electricity, an electrolyte. Some solutions are strong electrolytes while others are weak electrolytes. 1. What do you think is giving rise to electrical conductivity? ions in a crystal 2. This is a diagram showing ions in a crystal. Draw a diagram showing the particles in 1) strong electrolyte, and 2) weak electrolyte. Pay attention to how the water molecules will interact with each ion. strong electrolyte weak electrolyte A solution was made by dissolving 1o.0 g of potassium sulfate in 250.00 mL of solution. (Show all work; use back of paper if needed) 3. a. How many moles of potassium sulfate are in solution? b. How many moles of each ion are in solution? c. What is the concentration of potassium sulfate? Each ion?
