Question

1. substance that releases hydroxide ions (oh) when dissolved in water; a basic solution has a ph greater than 7.

a. salts
b. acids
c. sugars
d. bases

1. substance that is dissolved.

a. colloid
b. compound
c. solvent
d. solute

1. uneven distribution of electrons; one side is more positive the other side is more negative.

a. cohesion
b. adhesion
c. solution
d. polarity

1. water’s tendency to form hydrogen bonds with substances other than water.

a. cohesion
b. adhesion
c. viscosity
d. polarity

Explanation:

1. Bases release OH⁻ ions in water, making solutions basic (pH >7).
2. Solute is the substance dissolved in a solution.
3. Polarity arises from uneven electron distribution, creating positive/negative sides.
4. Adhesion is water's H-bonding with other substances (vs. cohesion with water).

Answer:

1. d. Bases
2. d. Solute
3. d. Polarity
4. b. Adhesion
