Module #40 You have been given a solution that might contain any of the following cations: Cd2+, Ag*, Cr³+, and Ca²+ Addition of excess HCI causes a precipitate to form. This precipitate is filtered off. An excess of H₂SO4 is added to the remaining solution, causing a second precipitate to form. The second precipitate is filtered off and NaOH is added to the remaining solution until it is strongly alkaline. No precipitate forms. Using the solubility rules found in your lab manual and/or text book, identify whether or not each cation was initially present in the original solution. Cr³+ (aq) choose.. 0 Cd2(aq) Choose... Ag (aq) Present in original solution. Not present in original solution Ca² (aq) Not enough information given in question
