Measure volume of alkali using a volumetric pipette, Place alkali in conical flask, Add a few drops of indicator to the alkali in the volumetric flask, Fill burette with acid using a burette funnel, Record initial reading on the burette, Add acid until the indicator changes colour, Record final reading on the burette, Calculate the titre (inital -final), Use the volume of the titre to repeat the titration without indicator, Put the salt solution in an evaporating dish, Heat the evaporating dish over a water bath, Pour the concentrated / saturated salt solution into an crystallising dish, Allow the water to evaporate from the crystallising dish, When the crystals have formed either scrape them from the crystallising dish or filter the mixture and collect, wash and dry the residue, or filter the mixture and collect, wash and dry the residue.
