Use the following information to answer numerical-response question 14 and question 42. Arsenic acid, H3AsO4(aq), has limited uses because of its toxicity, but it has occasionally been used in wood preservatives and as a finishing agent for glass and metal. The following equations represent the reactions that may occur when arsenic acid reacts with water. 14. Numerical Response The K, value for H₂ASO4 (aq), expressed in scientific notation, is a.b x 10-cd. The values of a, b, c, and d are, respectively, . and a H3AsO4(aq) + H₂O(1) H₂AsO4 (aq) + H₂O(1) HASO2 (aq) + H₂O(1) = AsO³(aq) + H₂O*(aq) H₂AsO4 (aq) + H₂O*(aq) HASO4 (aq) + H₂O*(aq) Row A. B. C.
