Bases And Acids; How Much Do I Know?
Let's find out how much we know about acidic and basic solutions.
Questions and Answers
- 1.
Acids are electron acceptors.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Acids are considered electron acceptors or proton donors. Bases are proton acceptors. Acids give off a hydrogen ion (a proton). Bases like to give off hydroxide ions (OH-).Rate this question:

What is the term for the positive and negative ions of a compound breaking apart in solution?
- A.
Conglomeration
- B.
Oxidation
- C.
Dissociation
- D.
None of the above
Correct Answer
C. DissociationExplanation
Acids and bases go through a process of dissociation when they are put into solution. They break apart into positively and negatively charged particles.Rate this question:

PH is a measure of ____ ions.
- A.
Hydroxide
- B.
Hydrogen
- C.
Aqueous
- D.
None of the above
Correct Answer
B. HydrogenExplanation
pH is a measure of hydrogen ions (H+). Hydrogen ions have lost their electron and become protons. pOH is a measure of hydroxide ions (OH-) in solution.Rate this question:

What is the term for a water molecule that gains an extra hydrogen ion?
- A.
Hydroxium ion
- B.
Hydronium Ion
- C.
Hydroxide ion
- D.
None of the above
Correct Answer
B. Hydronium IonExplanation
A hydronium ion has three hydrogen atoms and one oxygen atom (H30+). Hydronium molecules are water molecules with a positive charge.Rate this question:

An aqueous solution is one that has compounds dissolved in water.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
An aqueous solution is one where the solvent is water. Acids and bases are often placed in water to dilute them.Rate this question:

A docids and bases can combine to create water and salts.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Acids and bases combine to create water and salts. Sodium hydroxide (NaOH) and hydrochloric acid (HCl) can combine to form water (H2O) and sodium chloride (NaCl). Sodium chloride is the salt.Rate this question:
