Understanding Acids and Bases

What characterizes a strong acid in terms of ionization?

• It ionizes only in the presence of a base.

• It does not ionize at all.

• It ionizes partially.

• It ionizes completely.

Which of the following is true about weak acids?

• They ionize only in the presence of a strong base.

• They ionize very little to moderately.

• They do not ionize at all.

• They ionize completely.

What happens when a weak acid reaches equilibrium?

• It converts entirely into its ionized form.

• It stops ionizing completely.

• It maintains a balance between ionized and non-ionized forms.

• It continues to ionize completely.

What does a high dissociation constant indicate about an acid?

• The acid is neutral.

• The acid does not ionize.

• The acid is strong.

• The acid is weak.

How does a strong base behave in solution?

• It ionizes only in the presence of an acid.

• It does not ionize.

• It ionizes partially.

• It ionizes completely.

What is the main difference between strong and weak bases?

• The amount of OH- ions they contribute to the solution.

• The color they turn in a solution.

• Their ability to dissolve in water.

• Their reaction with acids.

What is the primary factor in determining if a substance is a strong acid or base?

• Its smell.

• Its color in solution.

• Its ability to ionize completely.

• Its taste.

What does water need to do to be considered an acid or a base?

• Contribute H+ ions only.

• Contribute OH- ions only.

• Contribute either H+ or OH- ions and ionize.

• Not ionize at all.

Which of the following is NOT part of the checklist for determining if water is an acid or base?

• Does it contribute OH- ions?

• Does it change color?

• Does it ionize?

• Does it contribute H+ ions?

What is the role of ionization in classifying acids and bases?

• It determines the color of the solution.

• It determines the strength of the acid or base.

• It determines the smell of the solution.

• It determines the taste of the solution.
