Question

Each of the following reactions shows a solute dissolved in water. Classify each solute as a strong electrolyte, a weak electrolyte, or a nonelectrolyte. A(l)→A(aq) BC(aq)⇌ B+(aq)+C−(aq) DE(aq)→D+(aq)+E−(aq) XY(s)→X+(aq)+Y−(aq) Z(s)→Z(aq) Drag the appropriate items to their respective bins.

Answer 1

Answer:

A(l)→A(aq) - Nonelectrolyte

BC(aq)⇌ B+(aq)+C−(aq) - Weak electrolyte

DE(aq)→D+(aq)+E−(aq) - Strong electrolyte

XY(s)→X+(aq)+Y−(aq) - Strong electrolyte

Z(s)→Z(aq) - Nonelectrolyte

Explanation:

An electrolyte that, when dissolved in water, allows the water to conduct electricity. Electrolytes are ionic compounds that dissociate into their constituent ions when dissolved in water. Strong electrolytes dissociate completely while weak electrolytes do not dissociate completely. A nonelectrolyte does not allow water to conduct electricity and does not break apart when dissolved in water.

A and Z are nonelectrolytes since they do not separate into a positive and negative part when dissolved in water

BC, DE, and XY are electrolytes since they dissociate into their constituent ions when dissolved in water. BC is a weak electrolyte since the ions are in equilibrium with the compound BC, meaning that BC doesn't dissociate completely. DE and XY are strong electrolytes since they dissociate completely as indicated by the forward arrow.

Answer 2

Answer:

A(l)→A(aq) -Non electrolyte

BC(aq)⇌ B+(aq)+C−(aq) - Weak electrolyte

DE(aq)→D+(aq)+E−(aq) - Strong electrolyte

XY(s)→X+(aq)+Y−(aq) -Strong electrolyte

Z(s)→Z(aq) - Non-electrolyte

Explanation:

• An electrolyte is a substance that is either in a molten or aqueous form that ionizes when dissolved in water and conducts an electric current when passed through it.
• Non-electrolytes, therefore, do not ionize when dissolved in water to form free ions and thus do not conduct electric current.
• Electrolytes may be classified as strong or weak electrolytes.
• Strong electrolytes such as strong acids and bases are those electrolytes that ionize completely to form ions that are responsible for the conduction of electricity.
• Weak electrolytes on the other hand partially ionize to yield ions. They include weak acids such as acetic acids and weak bases.
