When 0.27g of aluminium is added to excess copper(II) sulphate solution,0.96g of copper is precipitated. deduce the equation for the reaction
- 己式庚辛Lv 710 年前最愛解答
the equation should be something like
aAl + bCuSO4 ------> (a/2)Al2(SO4)3 + bCu
OR aAl + bCu(2+) ------> aAl(3+) + bCu
now, find out the no. of mole of each metal.
no. of mole of Cu = mass / molar mass = 0.96/63.5 = ... mole
no. of mole of Al = 0.27/27.0 = ... mole
then, you'll know the mole ratio of Al : Cu, which is equal to a/b .
if you want to check your steps of calculations or answers, post it up.
and others, PLEASE, do not directly post the answers.
