Below are the balanced equations for the reactions in Parts 13. Review the results of your
experiments and look closely over the mole ratios of the chemical reactions. Do your experiments reflect the stoichiometric, molar amounts indicated by the reactions? Discuss this using the evidence from your experiments.

 

Cu(NO3)2 (aq) + 2NaOH (aq)  Cu(OH)2 (s) + 2NaNO3 (aq)  Note: Cu(OH)2 is a blue precipitate.

FeSO4 (aq) + 2NaOH (aq)  Fe(OH)2 (s) + Na2SO4 (aq)  Note: Fe(OH)2 is a dark green precipitate.

Fe(NO3)3 (aq) + 3NaOH (aq)  Fe(OH)3 (s) + 3NaNO3 (aq) Note: Fe(OH)3 is a red­orange precipitate
