Heat on a steam bath until effervescence stops. Cool, and titrate with 1N hydrochloric acid using phenolphthalein indicator. Carry out a blank titration using 3 ml water in place of the formaldehyde.\n1 ml of 1N sodium hydroxide ≡ 0.0300 g formaldehyde\nstrength of formaldehyde solution ≡\n(B-T)×0.0300×100g3per100ml where:\nB = blank titre; and\nT = sample titre.",
