Three unknown acid solutions are labeled A, B, and C. One is sulfuric acid, one is hydrochloric acid, and the other s nitric acid. Each has a concentration of approximately one molar. Using only aqueous regents of 0.20 M lead (II) nitrate and 0.50 M calcium nitrate, write a short, concise experimental procedure, the results of which will be sufficient to identify each of the unknown acids. Tell what you would expect to see and what it means. Write net ionic equations to illustrate your answer.
