react together

Barium Barium sulphatesulphate

14

answer

eymmcl2003

NaOH + HNO3 NaNO3 + H2OIn a titration, 20cm3 of sodium hydroxide

was neutralised by 15cm3 of 0.2 mol/l nitric acid. Calculate the concentration of

the sodium hydroxide solution.

15

answerCVH+ (acid) = CVOH- (alkali)

0.2 x15x1 = Cx20x1

3= C x 20

C = 3/20 = 0.15 mol/l
