Textbook J.9)

[asheagg3I]

Hi,

I'm very confused about how to answer this question.
J.9 Identify the salt that is produced from the acid–base neutralization reaction between (a) potassium hydroxide and acetic acid,
(b) ammonia and phosphoric acid; (c) calcium hydroxide and bromous acid; (d) sodium hydroxide and hydrosulfuric acid,
(both atoms react). Write the complete ionic equation for each reaction.

Can someone explain where to start.

Hello! I can walk you through the steps that I did to solve these problems.

For me, I start with writing out the reactants. I'll use d (sodium hydroxide and hydrosulfuric acid) as an example. So that would look like this:
NaOH(aq) + H2S(aq)

Then, I would figure out which is the base and which is the acid, and dissociate the base. Here, the base is NaOH and the acid is H2S:
Na+(aq) + OH-(aq) + H2S(aq)

Next, I figure out the products based on this dissociation. In this case, the OH- and the H2 from the hydrosulfuric acid (because the problem says both hydrogens react) would form water, leaving a sodium and sulfur ion:
Na+(aq) + OH-(aq) + H2S(aq) -> Na+(aq) + S2-(aq)- + H2O(l)

Finally, I balance the equation:
2Na+(aq) + 2OH-(aq) + H2S(aq) -> 2Na+(aq) + S2-(aq) + 2H2O(l)

Hopefully this helps!
