A weak acid is defined as an acid that ["dissociates completely in solution", "does not dissociate at all in solution", "does not burn as much as a strong acid", "dissociates partially, but not completely, in solution"]
and has a Ka value that is larger than ["1.00 x 10^(-7)", "1.00 x 10^14", "1.00", "1.00 x 10^(-14)", "7.00", "0.00"]
and lower than ["1.00 x 10^(-14)", "1.00", "0.00", "7.00", "1.00 x 10^(-7)"] .
Homework Answers
The weak acid is the acid does not dissociate completely instead it dissociate partially.
The answer is 1) A weak acid is defined as an acid that "dissociates partially, but not completely, in solution".
As the weak acid dissociates partially its dissociation constant is larger than "0.00" but it is not more than "1.00".
