A solution is believed to contain one or more of the following ions: Cr 3+ , Zn
Question:
A solution is believed to contain one or more of the following ions: Cr3+, Zn2+, Fe3+, Ni2+. When the solution is treated with excess NaOH(aq), a precipitate forms. The solution in contact with the precipitate is colorless. The precipitate is dissolved in HCl(aq), and the resulting solution is treated with NH3(aq). No precipitation occurs. Based solely on these observations, what conclusions can you draw about the ions present in the original solution? That is, which ion(s) are likely present, which are most likely not present, and about which can we not be certain? Refer to Appendix D for solubility product and complex-ion formation data.
