Precipitate

Precipitates form when two salt solutions mix to create an insoluble product. They also occur when a solution becomes saturated, often due to cooling or evaporation, causing excess solute to precipitate out.

What happens when two solutions of salts are mixed?

• They form a soluble product.

• They do not react.

• They form an insoluble product.

• They evaporate completely.

Which of the following can cause a solution to form a precipitate?

• Adding more solvent

• Stirring the solution

• Increasing the temperature

• Cooling the solution

What is a common result when a solution is cooled?

• The solute precipitates out

• The solute evaporates

• The solute dissolves more

• The solution becomes more concentrated

What occurs when a solution reaches its saturation point?

• The solute dissolves completely

• The solute remains unchanged

• The solution becomes less dense

• The excess solute precipitates out

Which process does not lead to precipitation?

• Mixing two salt solutions

• Cooling a solution

• Evaporating a solution

• Heating a solution
