Question

****I have attempted these all on my own and I cannot get them correct. Please only respond if you are confident in your answer, because I only have a few attempts allowed. Also, I am looking for a good explanation of how to work these out on my own*****

Write net Bronsted equations and determine the equilibrium constants for the acid-base reactions that occur when aqueous solutions of the following are mixed.

Instructions:

Enter all substances in the order listed at the top of the column.

Use a carot to indicate a superscript, but do nothing for subscripts.

Use a hyphen + greater than (->) for yields.

Report K to three sig figs even though it is good to only two.

Group 1A and 7A ions (except fluoride) are spectator ions.

Reactants Rxn: Acid(1) + Base(2) = Base(1) + Acid(2) K (three sig figs) acetic acid + ammonia    hydrochloric acid + sodium hydroxide    hydrazoic acid + sodium hypochlorite KHSO4 + NH3    H2S + KClO

Explanation / Answer

1. acetic acid + ammonia

NH3 + H2O -> NH4OH

NH4OH + CH3COOH -> CH3COO- + NH4+ + H2O

2. hydrochloric acid + sodium hydroxide

HCl + NaOH -> Na+ + Cl- + H2O

3. hydrazoic acid + sodium hypochlorite

HN3 + NaOCl -> NaN3 + HOCl

4. KHSO4 + NH3

KHSO4 + NH3 -> NH4+ + KSO4-
