Question

When the following solutions are mixed together, what precipitate (if any) will forms? Write the reaction equation for all the cases and write the net ionic equation for only those reactions that react:

potassium nitrate solution and barium acetate

I am seriously lost on this, this is the only one out of 6 that I cannot do for some reason. I've been doing chem since 4 today.

Answer 1

There is no reaction.
Look up the solubility of these.
KNO3 is soluble
Ba(C2H3O2)2 is soluble.

Now look at the possible products if they react as double displacement.
KC2H3O2 is soluble
and Ba(NO3)2 is soluble.
Neither of the possible products is a gas.
Neither is a weak electrolyte.

Reactions occur for the following reasons:
a ppt is formed.
a gas is formed
a weak electrolyte (like H2O) is formed.
a redox reaction occurs.
