Webb12 aug. 2024 · If you add sulphuric acid slowly, the local acid concentration will remain rather low and the reaction mixture is rapidly homogenised. This means that side reactions caused by sulphuric acid will be suppressed. If, however, you add it quickly, there will be areas of your solution with very high local sulphuric acid concentrations. WebbSlowly add a drop or two (Pasteur Pipet) of the reaction mixture onto the ice with swirling. Once crystals of the product begin to form, slowly add the remainder of the reaction mixture, dropwise with swirling. Allow the ice to melt.
