Did you know?
WebThe conjugate base of a weak acid is? a) a strong base b) a weak base c) a weak acid d) a strong acid e) none of the above I selected a strong base but this answer was incorrect. Why is this the wrong answer? I thought a strong acid has a weak conjugate base or a strong base has a weak conjugate acid. WebA weak monoprotic base has a K b = 2.94 × 10 −7. Calculate the K a for the conjugate acid of this base. Report your answer to THREE significant figures. You may (but are not required to) enter your answer in scientific notation; for example, if your answer is 2.44 × 10-2, you would enter 2.44E-2. The E must be uppercase. 1c.
