25 cm^3 of a solution of known 0.2M HCl is neutralised by titration by 21.5cm^3 of NaOH solution. Calculate then concentration of the NaOH solution to 3dp.

Recall n = c *(v/1000) if the volume is in Cm 3 . Now, n(HCl)= 0.2 x (25.0/1000) n(HCl) = 5x10 -3 Since the relationship stoichiometrically is 1:1 (H + : OH - ), we can infer that n(NaOH) = 5x10 -3 and by re...
