Identify each of the following household substances as a strong electrolyte, weak electrolyte, or non-electrolyte: salt solution (in water), sugar solution (in water), bleach, vinegar, and baking soda solution (in water). Give reasoning for your assignment.

Answer:

Electrolytes are substances that can ionize in water. They could be acids, bases or salts as long as they give ions when they dissolve in water.

Explanation:

  • Strong electrolytes completely ionize when dissolved in water, leaving no neutral molecules. The strong electrolytes here are: salt water, baking soda (NaHCO3) solution.
  • Weak electrolytes do not completely dissociate in solution, and hence have a low ionic yield. Examples of this would be vinegar and bleach (which could be sodium hypochlorite or chlorine, which are weakly dissociated).
  • Non-electrolytes will remain as molecules and are not ionized in water at all. In this case, sugar solution is a non-electrolytes, even though sugar dissolves in water, but it remains as a whole molecule and not ions.

The categorization into strong, weak, or non-electrolyte would be:

Strong = salt water, baking soda solution.

Weak = vinegar and bleach

Non = sugar solution

What are electrolytes?

The electrolytes are characterized as the substances that generate electricity when it gets in the molten or ionized state.

The strong electrolytes are characterized as the ones that completely break up while weak ones do not break up completely.

While the non-electrolytes fail to dissolve at all in the water, and hence, they are called non-electrolyte.

They are categorized as mentioned above.
