Equation of reaction : 2NaOH + H2SO4 → Na2SO4 + 2H2O Concentration of a base, CB = 0.5M Volume of acid, VA = 10cm3 Concentration of an acid, CA = 1.25M Volume of base, VB = ? Recall:
CAVACBVB=nAnB ... (1)
N.B: From the equation,
nAnB=12 From (1)
1.25×100.5×VB=12
12.50.5VB=12
25 = 0.5VB VB = 50.0 cm3
