1. What is a property of a base? You should N-O-T taste laboratory chemicals!!! I don't know why textbooks emphasize the taste of acids and bases. But that is the answer.
2. In the reaction of aluminum bromide with ionized sodium bromide, which compound is the Lewis acid?
What reaction???
3 In a neutral solution the [H^+] is ____.
At 25C a solution is said to be neutral when the hydrogen ion concentration is 1.00x10^-7M.
4 With solutions of strong acids and strong bases, the word strong refer to ____.
The strength of electrolytes, including acids and bases, describes the degree to which the substance ionizes. Strong acids and bases ionize completely in water.

6. The ionization constant (K^a) of HF is 6.7 x 10^-4. Which of the following is true in a 0.1M solution of this acid?
a. [HF] is greater than [H^+][F^-].* == Yep
b. [HF] is less than [H^+][F^-]. == Nope
c. [HF] is equal to [H^+][F^-]. == if K=1
