Electrolito (química)

The video explains the electrical conductivity of solutions. When salt dissolves in water, it separates into chlorine and sodium ions, allowing the solution to conduct electricity. In contrast, sugar dissolves without forming ions, so sugar solutions do not conduct electricity.

What happens to salt when it is dissolved in water?

• It evaporates.

• It remains unchanged.

• It forms a solid precipitate.

• It dissociates into ions.

Why can salt solutions conduct electricity?

• Because they contain free-moving ions.

• Because they are heated.

• Because they are colorless.

• Because they are sweet.

Which of the following solutions is likely to conduct electricity?

• A solution of sand in water.

• A solution of oil in water.

• A solution of sugar in water.

• A solution of salt in water.

Which of the following is true about sugar solutions?

• They do not conduct electricity.

• They dissociate into ions.

• They form a gas.

• They conduct electricity well.

What is the main reason sugar solutions do not conduct electricity?

• Sugar molecules do not separate into ions.

• Sugar molecules are too large.

• Sugar solutions are too cold.

• Sugar solutions are too thick.
