Electrolytes and Ionic Compounds

The video explores whether potassium iodide (KI) is an electrolyte. It defines electrolytes as substances that dissolve in water to produce ions, enabling the solution to conduct electricity. KI is identified as an ionic compound composed of potassium and iodide ions. The video explains that KI is highly soluble in water, dissociating into K+ and I- ions, thus conducting electricity. Consequently, KI is classified as a strong electrolyte due to its complete ionization in water.

What is the primary characteristic of an electrolyte?

• It remains intact in water.

• It dissolves in non-polar solvents.

• It is always a solid.

• It produces ions in solution.
