Quiz Answer Key and Fun Facts
1. What is an Arrhenius Acid?

Answer: A substance which releases hydrogen ions in water

All Arrhenius Acids start with an H and are ionic substances. Common examples include HCl (hydrogen chloride) and HBr (hydrogen bromide).
2. Which of the following typically readily react with metals?

Answer: Acids

Acids react with metals, while bases generally do not (there are some exceptions). When acids react with metals they often release hydrogen gas.
3. What is the pH of water at 25 degrees c?

Answer: 7

Water is a neutral substance with an equal proportion of hydrogen and hydroxide ions in solution. At different temperatures the pH of water can vary, but it will always remain neutral.
4. When you add pH to pOH you always get _________.

Answer: 14

When the pH is known you can subtract it from fourteen to find the pOH. This information can be used to calculate concentration of ions.
5. What is an amphiprotic substance?

Answer: A substance that acts both as an acid and a base

An amphiprotic substance can either donate a proton, or accept a proton. This ability allows it to be defined both as an acid and a base.
6. What does a strong base do in solution?

Answer: becomes fully ionized

A strong base will become 100% ionized in solution, and a strong acid will fully dissociated in solution. Weak acids and bases set up an equilibrium where they don't fully dissociate.
7. What is the range of pH for a acid?

Answer: less than 7

Although the majority of substances will have a pH that falls between 0 and 14, there are some that fall outside of this range. Acidic substances are less than 7 and neutral substances have a pH of 7, while basic substances have a pH greater than 7.
8. What is an equivalence point?

Answer: The point where mol H+ =mol OH-

The equivalence point is also known as a stiochiometric point. It occurs when two substances are mixed until such time that the moles of hydrogen and hydroxide ions are equal.
9. What is Kw?

Answer: The ionization constant for water

Kw is equal to the concentration of hydrogen multiplied by the concentration of hydroxide. At 25 degrees C it is equivalent to 1.0 x 10^14.
10. What is a buffer solution?

Answer: A solution that resists pH changes

A buffer solution is designed to maintain a constant pH with the addition of small ammounts of acids or bases. They are made up of a weak acid and the soluble salt of its conjugate base or a weak base and the soluble salt of its conjugate acid.
