The method used to make the lead sulfate is: pour 100 cm3 lead nitrate solution into a beaker, add drops of sodium sulfate solution until a precipitate is seen , allow the precipitate to settle to the bottom of the beaker, pour off the liquid and use a spatula to transfer the solid lead sulfate onto a filter paper. Explain two ways of improving this experimental method in order to increase the amount and quality of lead sulfate that could be obtained from 100 cm3 of lead nitrate solution – 9039

1. I would add excess sodium sulfate solution instead of just a few drops so that more lead sulfate is formed. Then, I would filter the mixture instead of pouring off the liquid to make sure none of the lead sulfate is lost. After that, I would wash the lead sulfate to remove any impurities and then place it in a warm place to dry it properly.
