Question

what is the name of this ionic compound?
snc₂o₄
refer to a periodic table and a list of polyatomic ions.
tin(ii) oxalate tin(ii) bicarbonate
tin(iv) bicarbonate tin(iv) oxalate

Explanation:

• First, identify the cation and anion. The cation is Sn (tin). Since it is a transition metal, we need to determine its oxidation state.
• The anion is \(C_{2}O_{4}^{2 -}\) (oxalate ion, which has a charge of - 2).
• In the formula \(SnC_{2}O_{4}\), there is 1 Sn ion and 1 \(C_{2}O_{4}^{2 -}\) ion. Using the charge balance rule (the sum of the charges of cations and anions in a neutral compound is zero), if the charge of the anion is - 2, then the charge of Sn (cation) must be + 2.
• The naming rule for ionic compounds with transition metals: we use the oxidation state of the metal in Roman numerals in parentheses. So, Sn with an oxidation state of + 2 is named tin(II).
• The anion \(C_{2}O_{4}^{2 -}\) is named oxalate.

Answer:

tin(II) oxalate
