Precipitado (química)

Precipitates form when two salt solutions mix and react to produce an insoluble product. They also form when a solution cannot hold its solute load, often due to cooling or evaporation, leading to excess solute precipitation.

What happens when two solutions of salts are mixed and react?

• They form a precipitate.

• They evaporate completely.

• They form a soluble product.

• They become more dilute.

What is a precipitate?

• A soluble product formed in a reaction.

• A gaseous product formed in a reaction.

• An insoluble product formed in a reaction.

• A liquid product formed in a reaction.

Under what condition can a solution no longer hold its solute?

• When it is diluted.

• When it is cooled or evaporated.

• When it is heated.

• When it is stirred.

What can cause excess solute to precipitate from a solution?

• Adding more solvent.

• Decreasing the pressure.

• Increasing the temperature.

• Cooling or evaporation.

What is the result when a solution reaches its solute capacity due to cooling?

• The solution becomes more concentrated.

• The solute dissolves completely.

• A precipitate forms.

• The solution changes color.
