[9] The general basis for this divalent cation-divalent anion precipitate is elaborated later. In the vancomycin-daptomycin case, the sulfate salt of vancomycin indicates that vancomycin is a cation.

The conversion of carbon dioxide (CO2) into valuable chemical products via the electrochemical CO2 conversion reaction could ...

Ammonia is added to solutions of cobalt, nickel, and copper 2+ cations. First formation of the hydroxide precipitate is seen, then of the ammonia complex. Pour 0.1M solutions of Cu2+, Co2+, and Ni2+ ...

You will be asked to plan an experiment to identify the ions present in an unknown compound. These tables can help: Result Blue-green flame. Blue precipitate which remains when excess NaOH ...

A white precipitate forms if sulfate ions are present. Explain why, in a test for sulfate ions, the sample is acidified with hydrochloric acid first. Carbonate ions also produce a white ...
