To tell if a substance is an electrolyte or nonelectrolyte we first need to know what type of compound we have and if it will produce ions when dissolved in water.
Definition
An electrolyte is: a substance that dissolves in water (or other polar solvent) to produce ions and a solution that conducts electricity.
Classifying Electrolytes
Strong Electrolyte: completely dissociate in solution and conducts electricity. Soluble ionic compounds and strong acids are electrolytes.
Weak Electrolyte: partially dissociate in solution and poorly conduct electricity.
NonElectrolytes: do not dissociate into ions and do not conduct electricity. Most molecular compounds are nonelectrolytes.

Sports drinks, like Gatorade or Powerade, consist of primarily Potassium and Sodium electrolytes to provide hydration due to sweating. Other important electrolytes are chloride , calcium, magnesium, and phosphate. Drinks containing electrolytes are also used extensively in medicine for oral rehydration.

What are the key concepts the NCLEX wants RN nursing students and LPN students to know about fluid and electrolyte imbalances?
Fluid and electrolyte imbalances includes imbalances of the 6 electrolytes:
Potassium: Hyperkalemia \u0026 Hypokalemia
Sodium: Hypernatremia \u0026 Hyponatremia
Calcium: Hypercalcemia \u0026 Hypocalcemia
Magnesium: Hypermagnesemia \u0026 Hypomagnesemia
Chloride: Hyperchloremia \u0026 Hypochloremia
Phosphate: Hyperphosphatemia \u0026 Hypophosphatemia

Electrolytes
The term electrolyte is a term used when talking about solutions with water as the solvent. We demonstrate the property of being an electrolyte with an electrical conductivity tester like this.\r
\r
Pure water does not conduct electricity. I will put the electrodes of this apparatus into a beaker of pure water. There is no light coming from the light bulb. If I dissolve a material in this water and the light lights brightly, the dissolved material is called a strong electrolyte. \r
\r
As an example, here is a small amount of table salt. As I add it to the water and dissolve it, it dissolves by breaking into charged particles, the ions of sodium and chlorine, which now allow the solution to conduct electricity. So the ionic substance table salt is a strong electrolyte \r
\r
The term nonelectrolyte refers to a substance which dissolves in water but does not allow electrical conductivity. Here is some water and some sugar. As the sugar dissolves, the light does NOT light up. So sugar is a nonelectrolyte.\r
\r
Some acids and bases are also strong electrolytes. Here as an example is some hydrochloric acid. Only a little in the water allows the light to light up very brightly. So the acid is also a strong electrolyte and is called a strong acid.\r
\r
Acetic acid, on the other hand, dissolves but allows very little electricity to go through the water. See how the light bulb gives off much less light. Thus we call acetic acid a weak electrolyte and a weak acid.
