May 5, 2014 · Sodium Sulfate is an ionic compound formed by two ions, Sodium N a+ and Sulfate SO−2 4. In order for these two polyatomic ions to bond the charges must be equal and opposite. Therefore, it will take two +1 sodium ions to balance the one -2 sulfate ion. This will make the formula for Sodium Sulfate N a2SO4. I hope this was helpful. SMARTERTEACHER.
Feb 22, 2016 · Explanation: The sulfate ion, SO2− 4 is a very common ion counter ion, and has some aqueous solubility. In sulfate, the formal oxidation state of the sulfur is V I +, and the negative charges are assumed to be distributed to the oxygen centres. Bisulfates, H SO− 4, are also very common. Answer link. Na_2SO_4 The sulfate ion, SO_4^ (2-) is a ...
Oct 17, 2022 · Example 10.1 : Example 4: Write the formula for iron (III) chloride. First identify the cation and the anion in this compound. cation = iron (III) = Fe +3 anion = chloride = Cl -1. For a neutral compound, one Fe +3 is needed for every 3 Cl -1 The formula of the compound is FeCl 3.
