Help me with this;
For the second part of the analysis,you will be provided with hydrated crystal of oxalic acid (H2C204. 2H2O). weigh out accurately about 1.575g of oxalic acid in a weighing bottle. Dissolve the acid in a beaker, then transfer the solution completely to 250cm3 standard volunteer flask and make up to the mark. shake it to ensure uniformity. Fill the burette with your prepared oxalic acid solution. Pipette 25cm3 of the given NaOH solution and titrate this against your oxalic acid solution using two or three drops of phenolphthalein,as indicator. Repeat the titration until consistent litres are obtained. From your result.calculate
(1) The concentration of the oxalic acid solution in moldm3
(2).The concentration of the oxalic acid solution in g/dm3
(3) The percentage purity of the sample of oxalic acid

2. It would be nice to know the molarity of the NaOH. The problem can't be worked without it.
