hi, a new member here:)
we did a bunch of redox labs at school, and now we need to write the equations and balance them...
however, i have no idea how we're supposed to know the products in a redox reaction, because the teacher never covered that... she just showed us how to balance already written equations.
so here it goes:
stock solution: KMnO4 + H2SO4 -> ? (doesn't look like double displacement..?)
to NaBr, add water and stock solution, then mineral oil. shake well. record the color of layers.
well, what i got is that the purple stock solution turned yellow when added to NaBr. there seemed to be only 2 layers, though; oil and aqueous solution. but the oil was not involved in the reaction.
and the lab says that Mno4 produces Mn2+ and Br is a brown liquid... but it doesn't help, since i still cannot figure out what the products are!
so please help... if i learn how to do this one, i think i'll be okay with the 9 problems that are left.
thanks in advance:D
