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.Know More
Stirring rods are used to decant or pour liquids slowly. Slow pouring is essential when working with potentially hazardous chemicals that can react too quickly. Using the stir rod to decant liquid makes it easier to keep a precipitate in the bottom of the beaker, because the liquid pours more slowly, reducing the chances of it agitating the solid.
To induce crystallization in a recrystallization experiment, the glass stirring rod is scraped against the inside of the flask containing the solution.Learn more about Chemistry
A lightning rod conducts a positive charge up to meet the negative charge of a lightning strike, allowing the strike to hit the rod and travel through attached wires to an underground connection. This diverts the strike away from a building, preventing or lessening potential damage, according to About.com.Full Answer >
A glass stirring rod is a common piece of lab equipment used to mix or stir liquids and chemicals. These rods are thicker than a typical drinking straw, have rounded ends and are made from a special type of laboratory glassware called borosilicate. This glass is less affected by thermal stress and has a very low thermal expansion point, so it is less affected by heat than metals are.Full Answer >
Monosaccharides are simple sugars that are used primarily as a form of energy for the organisms that consume them. Glucose, which is present in many different types of foods around the world, is the most common type of monosaccharide and is used as an energy source for many animals, including humans. They can be obtained naturally or through a biological process known as hydrolysis performed on either glycosides or polysaccharides.Full Answer >
Sulphur is an essential mineral, as most proteins found in the body contain sulphur. It is also part of bodily fluids, fats and the minerals that make up the skeleton. Some bacteria need sulphur, in the form of hydrogen sulphide, to perform photosynthesis.Full Answer >
