An unknown sample was tested for its anion and cation components. For the cation test, it gave a blue solution upon the addition of excess NH3. For its anion test, it formed a precipitate upon the addition of Ba(NO3)2, and CH3COOH was added to its precipitate which resulted in no reaction. What is the identity of the salt in the solution? O a. Fe₂(SO4)3 O b. CuSO4 O C. FePO4 O d. CU3(PO4)2 An unknown solution formed a white precipitate upon the addition of 1.0M NaOH, but no precipitate was formed when NH³ was added. What could be the ion present in the solution? O a. Ca²+ O b. Fe³+ O C. Zn²+ O d. Cu²+
