25cm^3 of a solution of NaOH required 28cm^3 of 1.0 mol dm^-3 H2SO4 to neutralise it.
a)Write an equation for the reaction.
2NaOH + H2SO4 ==> Na2SO4 + 2H2O
b)How many moles of H2SO4 were needed?
mols H2SO4 = M x L = ?
c)How many moles of NaOH were thus neutralised?
?mol H2SO4 x (2 mol NaOH/1 mol H2SO4) = ?mol H2SO4 x 2/1 = x
d)How many moles of NaOH are there in 25cm^3 of solution?
Isn't this the same answer as part c?
