WebMar 26, 2024 · The primary function of a stirring rod is to stir solutions by hand. Stirring rods have other uses in the laboratory, however, including helping to decant liquid from containers, breaking up emulsions and inducing crystallization. Stirring rods are used to decant or pour liquids slowly. WebStyrofoam Cup Calorimeter Procedure Heat Capacity of Calorimeter a With a graduated cylinder, measure out 50 mL of distilled water at room temperature. Transfer it to the clean dry calorimeter, which is mounted on a stirring plate and fitted with a digital thermometer calibrated to +0.1 °C.
Web5. Slowly pour the HCl solution into the calorimeter. Mix the contents of the calorimeter with the stirring rod. 6. Place the lid on the calorimeter. Place the thermometer in the mixture immediately. Measure and record the maximum temperature reached by the contents of the calorimeter. 7. Repeat steps 2 − 7 for a second trial. 8. WebYou can make a lid out of aluminum foil, paper, or cut a sheet of styrofoam or cardboard to fit. The lid should have two small holes, one for the thermometer, one for the stirring …
