Question #43441

What volume of 0.1 M NaOH is needed to titrate 100 mL of 0.2 M H2SO4?

a) 50 mL

b) 100 mL

c) 200 mL

d) 400 mL

a) 50 mL

b) 100 mL

c) 200 mL

d) 400 mL

Expert's answer

2NaOH + H

n(NaOH) = 2n(H

V(NaOH) = 2c(H

So, the correct option is (d): 400 mL

_{2}SO_{4}--> Na_{2}SO_{4}+ 2H_{2}On(NaOH) = 2n(H

_{2}SO_{4}), => c(NaOH)V(NaOH) = 2c(H_{2}SO_{4})V(H_{2}SO_{4})V(NaOH) = 2c(H

_{2}SO_{4})V(H_{2}SO_{4})/c(NaOH) = (2 * 0.2 M * 100 mL) / 0.1 M = 400 mLSo, the correct option is (d): 400 mL
