Hi,
can anyone help me with determining the result of this chemical formula? ???
(NH4)2SO4 + H3PO4 + KCl = .+H2O.
or
(NH4)2SO4 + H3PO4 + KOH = .+H2O.
the reaction is exothermic and results in a slurry-mud like substance which turned into solid after sometimes.
thanks.

Chemical formula describes composition of a compound.
(NH4)2SO4 + H3PO4 + KCl = .+H2O.
This is unfinished (and unbalanced) chemical reaction equation.

Determining a reaction can be a little difficult sometimes, especially in a case like youres, with more than one or two reactants. It's also hard to use you observations to predict anything:
the reaction is exothermic
In the second case, acid plus KOH is itself exothermic. So we can't be sure your observation describes the other reaction you're looking for.
and results in a slurry-mud like substance which turned into solid after sometimes.
This also, will depend more on how you mix things, than the real reaction. For example, a 100 ml of a 0.1 M concentration of each reactant, that forms a solid? It might, I don't know. Or are you mixing these reactants essentially pure, in just a bit of water to make a paste? Is that why you get a slurry? I assumed these were each in aqueous solution, or are you mixing them dry in a furnace of some sort?

Also worth considering is whether you're trying to make a reactant in situ, or 'on the spot'. Phosphoric (V) Acid with KCl will give HCl (g). So are you actually trying to use the HCl (g) or is it just a byproduct while you use the KH2PO4 instead?

That link might be useful in deciding which one you're making.
