Chemistry help, determining the states of matter (solid, liquid, Gas, Aqueous solution)

ok so we've done three chemical reactions coming up i.e

Mg(SO4)(aq) + NaOH(aq) YIELD MgOH(?) + Na2So4(?)

and it produced a substance with a jelly like characteristics with liquid on the top. My question is which one of the end products would be classified as a solid and which would be classified as an aqueous solution (ps i know the equations not balanced) Na2SO4 was a common end product and something bonded to an -OH group in all three reactions (and all three reactions had the jelly like substance in the product via visual observations)

magnesium hydroxide, Mg(OH)2 is a solid.
sodium sulfate Na2SO4 is aqueous

Best bet is to consult the solubility rules like:

Relevant items:
group 1 metals, nitrates, acetates, halides, are soluble: (so NaOH and Na2SO4 are (aq))
most SO4^2- compounds are soluble (so MgSO4 is (aq))
most hydroxides are not soluble. (so Mg(OH)2 is mostly (s) )

MgOH is solid...

Solubility of Na2SO4 in water is very high and solubility of Mg(OH)2 is pretty low, generally hydroxides of II.A and d-elements are not very soluble in water and they precipitate...

M(n+) + nOH(-) --> M(OH)n (precipitate) (M is metal from II.A, d-block or III.A)
