J.9

Postby Cavalli_1H » Tue Dec 03, 2019 5:30 pm

"Identify the salt that is produced from the acid-base neutralization reaction between (a) potassium hydroxide and acetic acid (b),(c) etc..."

What is a good way to approach this? I know that one product would have to be H2O, but other than that I'm not really sure where to go from there.

Well, neutralization reactions between acids and bases always form water and salt, so since you know that water will always be a product, you can write the conjugate bases and acids for the reactants and attempt to combine them. In the first example, the conjugates are K+ and CH3COO-, which you can combine to form KCH3COO, a salt. If the charges are different, then cross them to find the quantity of each individual reactant you need.

After taking out H2O because you know water and a salt are formed, try combining the anion of one molecule with the cation of the other to find the salt.

Does anybody have the answers to this problem? I tried to identify the salts but am not sure if I did it right.

The answer to part a is CH3CO2K, potassium acetate. part b is (NH4)3P04, ammonium phosphate. part c is Ca(BrO2)2, calcium bromite. Part d is Na2S, sodium sulfide.
