IB Chemistry - Practical Report Name: Chris Bolton Partner: Jamie Gearing Date(s) Conducted: 20/08/04 Topic: Acids and Bases Experiment: Neutralisation of Polyprotic Acids Aim: To produce two different metal salts (NaHSO4 and Na2SO4) through an application of specific stoichiometric ratios in a reaction of diprotic sulfuric acid (H2SO4) with sodium hydroxide (NaOH). Apparatus: Refer to attached worksheet for given apparatus and materials Method: Refer to attached worksheet for given method AMMENDMENTS/ADDITIONS/SAFETY PRECAUTIONS: * Avoid adding excess solution to evaporating basins whilst hot, as this may cause damage to the basins * Evaporate only a small volume of the evolved acids to reduce time required to produce the stock solution * Note: as acids evaporate small quantities of the salt may splatter - ensure that safety glasses are on securely * Do not add distilled water (for the stock solution) directly to the basins, rather wait momentarily for some cooling to occur * Agitate evolved solutions prior to evaporation to ensure homogeneity * To test the ?pH of
