Question

which of the following is not a multivalent ion? cu+ ag+ sb5+ cr3+

Explanation:

A multivalent ion can have multiple oxidation states. Silver (\(Ag\)) typically only forms \(Ag^{+}\) in its common ionic form. Copper (\(Cu\)) can be \(Cu^{+}\) or \(Cu^{2+}\), antimony (\(Sb\)) can have \(Sb^{3+}\) or \(Sb^{5+}\), and chromium (\(Cr\)) can have \(Cr^{2+}\), \(Cr^{3+}\) etc. So \(Ag^{+}\) is not a multivalent ion.

Answer:

B. \(Ag^{+}\)
