Quizplus · Accepted Answer

According to the question, K_a for formic acid is given. We need to calculate K_b for the formate ion. We can use the relationship between the acid and its conjugate base to calculate this value. K_a * K_b = K_w where K_w is the ionization constant of water, which is a constant. Therefore, K_b = K_w/ K_a Hence, the answer is option B.
