NaOH:
Cm=0,25mol/dm3
v=0,1dm3
n=Cm*v
n=0,25*0,1
n=0,025mola
H2SO4:
Cm=0,1mol/dm3
v=0,2dm3
n=0,1*0,2
n=0,02mola
2NaOH + H2SO4 ---> Na2SO4 + 2H2O
2mole NaOH ------ 1mol H2SO4
0,025mola NaOH ---- xmola H2SO4
x = 0,0125mola H2SO4 (kwasu użyto w nadmiarze)
2mole NaOH ----- 142g soli
0,025mola NaOH ---- xg soli
x = 1,775g soli
