Because the oxide ion is basic, metal oxides react readily with acids.
(a) Write the net ionic equation for the following reaction. (Use the lowest possible coefficients. Include states-of-matter under SATP conditions in your answer.)
FeO(s) + 2 HClO4(aq) Fe(ClO4)2(aq) + H2O(l)
i know the ansewr is FeO(s) + 2H^+(aq) --> Fe^2+(aq) + H_2O(l)but i do not know why. how do you know that HClo4 and Feclo4 split?
One of the reaction types you memorize. acid + base = salt + water.
base (FeO) + acid(HClO4) = salt [Fe(ClO4)] + water (H2O).
Use the solubility rules. If a compound is aqueous it splits into its ions, while if it is a solid (like FeO) or a liquid (like H2O) they ions do not separate. Hope this helps!
When dealing with acids and dissociating, remember that only certain acids dissociate. Those are the strong acids and they are: HCl, HBr, HI, NHO_3, H_2SO_4, HClO_3, and HClO_4. All other acids not listed are weak acids. Perchlorate splits because it is a strong acid. Remember that even if it says it is aqueous because it is an acid (all acids are aqueous), it may not dissociate because it could be a weak acid!
According to solubility rules, all soluble salts dissociate, and FeClO_4 is considered a soluble salt. Hope this helps!
To understand why the reactants and products in the given chemical equation are written the way they are, we need to examine the chemical properties of the compounds involved.
Iron(II) oxide (FeO) is a metal oxide, which means it contains the oxide ion (O2-) and a metal cation (Fe2+). Metal oxides are basic in nature and readily react with acids.
Hydrochloric acid (HClO4) is a strong acid that dissociates completely in water, producing hydrogen ions (H+) and perchlorate ions (ClO4-) in solution.
When FeO reacts with HClO4, the oxide ion in FeO reacts with the hydrogen ions from HClO4. This results in the formation of a metal cation, Fe2+, and water (H2O) as a product. The complete balanced equation for the reaction is:
FeO(s) + 2 HClO4(aq) → Fe(ClO4)2(aq) + H2O(l)
To write the net ionic equation, we only consider the species that are directly involved in the chemical change. In this case, the metal cation Fe2+ and the hydrogen ions H+ are the main species that undergo a reaction. The perchlorate ions (ClO4-) are spectator ions, meaning they do not participate in the chemical change.
The net ionic equation for the given reaction is:
FeO(s) + 2 H+(aq) → Fe2+(aq) + H2O(l)
So, FeO reacts with 2 H+ ions to form Fe2+ ions and water as the only products.
