Write balanced ionic equations for solutions of iron(III) nitrate and sodium carbonate ?
Write balanced ionic equations for the following chemical reactions. Include all relevant equilibrium equations.
When solutions of iron(III) nitrate and sodium carbonate are mixed, a precipitate of iron(III) hydroxide is obtained.
Faty,
First, we need to recognize that sodium carbonate in aqueous solution is rather alkaline; a way to represent that would be:
Na2CO3 + H2O = 2Na+ + HCO3- + OH-
Couple this with the dissolution of iron(III) nitrate), and the information given that iron(III) hydroxide is formed, and here is our equation:
Fe(NO3)3(aq) + 3Na2CO3(aq) + 3H2O ---> Fe(OH)3(s) + 6Na+(aq) + 3HCO3-(aq)
Hope that helped!
