How to standardise given NaOH solution? since NaOH is basic in nature. We should make a standard solution having acidic nature. Prepare a standard solution of ocalic acid (.1N)by dissolving 0. 63g of ocalic acid crystals in a 100ml flask. Make the solution up to the mark. Shake it well for the uniform concentration. The given NaOH solution is taken in the brunette. Pipette out 10ml of std ocalic acid solution to a conicalflask. Add phenolphthalein indicator. Iterate against NaOH solution till the appearance of pink colour.Repeat the iterations till concurrent values are obtained.
