What is the pK_a and general acid strength of formic acid if its conjugate base form has a pK_b of 10.23? A) 3.77 - fairly strong weak acid B) 5.99 - moderately strong weak acid C) 14.00 - not an acid but rather a strong base D) 3.23 - fairly strong weak acid E) cannot be determined from the information given

Question

Quizplus · Accepted Answer

The pKa of an acid and the pKb of its conjugate base are related by the equation pKa + pKb = 14.00. Given the pKb of the conjugate base of formic acid is 10.23, the pKa of formic acid is 14.00 - 10.23 = 3.77, making it a fairly strong weak acid.
