1. Solutions of potassium hydroxide and propanoic acid are mixed

This is all i have so far: KOH + C3H6O2
i believe the potassium hydroxide breaks up right? into K+ OH-

2.A solution of iron (11) chloride is added to an acidified solution of sodium dicrhromate

this is what i have so far: FeCl2 + Na2Cr2O7

(all the numbers are SUBSCRIPTS!)

thanx!!
