[constant thinker]

We did a titration lab in my chemistry class. We did 6 sets with various reactants and concentrations. One of the questions for my lab is to write all the equations. I just want to check to see that they are all right, which I'm pretty sure they are, and that the properties of salts formed are right. As a side note, I'm omitting the states (aqueous, liquid, etc.) because it'll just take more time to type, and they are all aqueous except for the water which is liquid. Wiki and google aren't really revealing the properties of the salts.

Set 1 (easy one)
HCl + NaOH --> NaCl + H₂O
The salt would have a neutral pH.

Set 2
KHC₈H₄O₄ + NaOH --> KNaC₈H₄O₄ + H₂O
I'm thinking the salt would be basic. Also, would this salt act as a buffer?

Set 3
H₂SO₄ + 2KOH --> K₂SO₄ + 2H₂O
This salt would have a neutral pH.

Set 4
H₂CO₃ + 2NH₄OH --> (NH₄)₂CO₃ + 2H₂O
I'm thinking that ammonium carbonate would be basic. I don't think it would act as a buffer, but I'm not sure.

Set 5
H₃PO₄ + 3NaOH --> Na₃PO₄ + 3H₂O
Trisodium phosphate is a slightly basic buffer. I'm pretty sure about that since phosphate salts are usually buffers, and are alkaline.

Set 6
HNO₃ + NH₄NO₃ + H₂O
Not entirely sure, but I think ammonium nitrate would be acidic (among being explosive  ).

The only reason why I care so much about the equations and the properties of the salts being right is because I've been helping people.
