Barney has discovered a new acid. Upon adding 15 grams of the new acid to water, he discovers that 4 grams of the acid dissociates. What should Barney classify this acid as?

Strong acid
Amphoteric acid
Buffer
Weak acid
Soluble acid

Explanation

Answer: D - Because this acid does not dissociate completely in small amounts in water, it is classified as a weak acid. Note that pretty much all acids are soluble in water, and as such answer E is not a good choice.
