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 so important and why you should always use the chemicals that you own for their intended purpose only. Otherwise, the repercussions could be disastrous to say the least. There are specific things that you and those around you should do when handling, storing or using chemicals in nearly every form.

Bubbles

Have you ever noticed that soap bubbles go up in winter and fall down in summer? The reason is that warm air is lighter than cold. And in winter the difference between the air temperature in the room (especially near the windows) and the one you exhale into the bubble is enough to overcome the heaviness of its shell.

Doublet

Two peaks or bands of about equal intensity appearing close together on a spectrogram.

Covalent Bond

Chemical bond formed by the sharing of one or more electron pairs between two atoms.

Turning iron nail into copper nail

This simple chemical experiment shows the so-called process of copper plating of metal products. Copper has the ability to deposit on a metal surface.
