Introduction Adropping funneloraddition funnelis a type oflaboratory glasswareused to transferliquids. They are fitted with astopcockwhich allows the flow to be controlled. Dropping funnels are useful for addingreagentsslowly, i.e. drop-wise. This is desirable when the quick addition of the reagent...
Introduction Commonly used in chemistry for reflux applications, such as Sechelt extraction; provides efficient cooling and condensation; ideal for food, pharmaceutical, and environmental industries; can be used to extract essential oils from plants, determine crude fat content, conduct laboratory-scale...
Introduction prevents internal short-circuiting of electrons. Internal short-circuiting implies the movement of electrons from the anode to cathode through the electrolyte, which dissipates the chemical energy without providing electrical potential in the external circuit. When the electrolyte is solid,...
Introduction Vapor that passes the thermometer condenses in the condenser, a double-walled tube that is cooled by water flowing through the outer layer, and drips into the receiver. Before moving on, let us look at benefits and drawbacks to...
