Understanding Dilute and Concentrated Solutions

What is the key characteristic of the terms 'dilute' and 'concentrated'?

• They are relative terms.

• They are absolute terms.

• They are unrelated to solute amount.

• They are synonyms.

In the example with two beakers, which solution is more concentrated?

• The one with 10 ml of solute.

• The one with 50 ml of solute.

• The one with 100 ml of solvent.

• The one with 20 ml of solute.

Why is the second beaker in the second example more concentrated?

• It has a higher proportion of solute.

• It has more solvent.

• It has less solute.

• It has a larger volume.

What is the main reason for adding acid to water instead of water to acid?

• Water is a poor heat absorber.

• Acid is a poor heat absorber.

• Water absorbs heat better than acid.

• Acid absorbs heat better than water.

What precaution should be taken when adding acid to water?

• Add water to acid instead.

• Add acid slowly and stir constantly.

• Do not stir the solution.

• Add acid quickly.
