Question

In an aqueous solution, strong electrolytes dissociates:
A. Completely
B. Partially
C. Sparingly
D. Incompletely

Answer 1

Hint:First, we need to understand the meaning of electrolyte. We all know that substances that produce ions when they get dissolved in water are known as electrolytes. We can divide electrolytes into acids, bases, and salts. As they all give ions when it is dissolved in water.

Complete answer:We have to remember that a strong electrolyte is one in which a solute gets completely, or almost completely, ionized or dissociated in a solution. The ions of strong electrolytes are good conductors of electric current in the solution. From the name "strong electrolyte" it can define it as a chemical substance that, when added in an aqueous solution, acts as a good conductor of electricity. Hence, we can say that it dissociates completely in the aqueous solution from the definition. Therefore, the option A is correct. Therefore we get to know that strong electrolytes dissociate completely in an aqueous solution.
The property that makes it a strong electrolyte is that a solute or solution that is an electrolyte that completely dissociates in solution. The solution will contain only ions and no molecules of the electrolyte. So, we can conclude that strong electrolytes are those which can be good conductors of electricity, but only in aqueous solutions or in the molten form.
Therefore, the option (A) is correct.

Note: After discussing strong electrolyte we need to understand about weak electrolyte. A weak electrolyte is an electrolyte that does not completely dissociate in an aqueous solution. Thus, the solution will have both ions and molecules of the electrolyte. For example, acetic acid is a weak electrolyte.
