Question

choose the best answers.
6.6 _ the properties of solvents and solutes change when they combine to make a solution.
a. can
b. cannot
6.7 _ solutions, like other types of mixtures, be separated into their individual parts.
a. cannot
b. can

Explanation:

• For 6.6: When solvents and solutes combine to form a solution, their properties can change. For example, salt (solute) has a certain property (crystalline, salty taste) and water (solvent) has its own properties (liquid, tasteless). When they form a salt - water solution, the taste and some physical properties (like density) change.
• For 6.7: Solutions are mixtures. Mixtures (including solutions) can be separated into their individual parts. For example, salt - water solution can be separated by evaporation (to get salt) and condensation (to get water back).

Answer:

6.6 A. can
6.7 B. can
