3) dissolve the solid in 100 cm3 of distilled water stirring with a glass rod
4) transfer the solution to a clean 250 cm3 volumetric flask using a funnel then rinse the beaker, funnel, glass rod
5) make up to below the mark with distilled water, insert the stopper and invert slowly several times to mix
6) using pipette transfer 25 cm3 of the solution into a conical flask
7) add 3-4 drops of methyl orange
