Identify the characteristics of ionic electrolytes Question Which of the following occurs when an ionic compound dissolves in a polar solvent such as water? Select all that apply: The water molecules chemically react with the ions. The disorder of the ionic salt is decreased. The water molecules attract both the anions and cations in the ionic salt. The ions become solvated water molecules, which reduces the electrostatic attractions between the ions.

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...

Define Electrolyte. 2. Solutions that are electrolytes have ions in solution. These ions are surrounded by layers of water molecules known as the solvation sphere. Ions with their solvation spheres are able to move freely about the solution and thus can be capable of transporting an electrical charge. For each of the following compounds identify the ions that will occur in solution. Compound Name Cation(s) Anion(s) BaCl2 barium chloride Ba² (29) 2 (24) Nas ZnBr2 FeCl3 LiOH AgC H:02 Mn(CIO)...
