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
Bromine is used in everyday products such as pesticides and water treatment solutions. Bromine is a reddish-brown gas that has a pungent smell and can irritate the skin, nose and eyes. Bromine was discovered in 1826 by A.J. Balard.Full Answer >
A pressurized water reactor uses a nuclear reaction to heat water. It then transfers that heat to a steam generator to drive an electric turbine. These reactors use two completely separate water loops to ensure no radioactive water or steam escapes the system. After the steam drives the turbine, it is condensed and flows back into the system, cooling the water in the primary loop, which then cools the reactor.Full Answer >
Lemonade is a mixture because sugar, water and lemons are combined together without a chemical reaction taking place. The bonds of the substances can't combine with one another, instead the three items are mixed up.Full Answer >
