Water's Role in Solutions

What word describes when water is attracted to other substances?

• cohesion
• adhesion
• capillary action
• surface tension

The attraction that causes water and other liquids to form drops is called ________________. This is also water’s ability to be attracted to other water molecules.

• adhesion
• capillary action
• cohesion
• surface tension

Type of mixture in which all substances are evenly distributed is a?

• Solution
• Solute
• Solvent

What is a solvent?

• The substance that does the dissolving in a solution.
• The substance that is being dissolved in a solution.
• The mixing of different substances.
• The process in which neutral molecules lose or gain electrons

In the above picture, a powder is about to be poured into the liquid. Which of the following should be done to make this powder dissolve faster?

• stir the powder in the liquid
• freeze the mixture
• add more powder to the liquid
• store the mixture in a dark place

A solution that is considered dilute would be....

• Dark in color
• Have a strong scent
• Have a large amount of solute
• Have a small amount of solute

When a solvent contains as much of the solute as it can hold, the solution is said to be

• supersaturated
• diluted
• saturated
• unsaturated

It is a maximum amount of solute that is soluble in 100 cm³ of solvent at a specific temperature.

This statement refers to

• Solute

• Solution

• Solubility

• Solvent

Diagram shows a UHT milk. It is example of ...

• Suspension

• Solute

• Colloids

Diagram shows experiment to study the effect if stirring and without stirring salts to its rate of solubility in water. Both beaker contain 100 cm³ of water.

What is the manipulated variable?

• Rate of solubility

• Temperature

• Volume if water

• Stirring and not stirring process
