    Chemistry can teach us about the composition of celestial bodies and determine their age.

  • Creating Malachite egg

    One of the most interesting and obvious chemical experiments is the experiment on the interaction of copper sulfate and calcium carbonate. The latter is contained in the shell of a simple egg, but copper sulphate should be searched in a chemical reagent store. This experience is simple, but...

  • What are Compound Microscopes?

    Most of the microscopes used today are compound. A compound microscope features two or more lenses. A hollow cylinder called the tube connects the two lenses. The top lens, the one people look through, is called the eyepiece. The bottom lens is known as the objective lens. Below the two lenses is...

  • Chemical Safety

    People use chemicals every day for a wide array of purposes, which can include work and house hold duties. Many of us fail to realize that we are actually handling potentially deadly chemicals when we simply clean the bathroom or wash the car. This brings to mind the reason why chemical safety is...

Common Ion Effect

Suppression of ionization of a weak electrolyte by the presence in the same solution of a strong electrolyte containing one of the same ions as the weak electrolyte.

Reversible Reaction

Reactions that do not go to completion and occur in both the forward and reverse direction.

Can water burn?

It’s known that water consists of atoms of molecules of oxygen and hydrogen. Since any compound with oxygen indicates the ability of the substance to burn, water is no exception. Thus, water has a surprising property of already "burnt out" compound.

Cathode Ray Tube

Closed glass tube containing a gas under low pressure, with electrodes near the ends and a luminescent screen at the end near the positive electrode, produces cathode rays when high voltage is applied.

Boiling Point Elevation

The increase in the boiling point of a solvent caused by the dissolution of a nonvolatile solute.

Faraday's Law of Electrolysis

One equivalent weight of a substance is produced at each electrode during the passage of 96,487 coulombs of charge through an electrolytic cell.

Ionization Constant

Equilibrium constant for the ionization of a weak electrolyte.

Hydration Energy

The energy change accompanying the hydration of a mole of gase and ions.

Mole Fraction

The number of moles of a component of a mixture divided by the total number of moles in the mixture.

 

Equivalence Point

The point at which chemically equivalent amounts of reactants have reacted.
