Explosive Chemicals - How Dangerous are They?

Many people have a natural fear of chemicals that catch fire easily.
In fact, I know of some people who became so nervous whenever
they have to come into the chemical areas that they lost their concentration
and fumble about with their activities, visibly shaken. It is as if the whole
place is going to explode in their faces anytime. However, if this natural
fear is allowed to paralyze us, there will not be any oil refinery, oil wells
or even petrol stations anywhere. Industrial processes will literally grind
to a halt. People will be so afraid to handle these chemicals in their work.
This article tries to eliminate this natural fear by explaining the properties
of flammable chemicals so that people will treat flammable chemicals with
respect but not with fear.

Water Softner

Water softener can be termed as a type of water filter, that helps to remove excess calcium, magnesium, bicarbonate and sulfate ions from water. This helps to eliminate the hardness of water and to avoid the common problems associated with hard water. This is achieved by replacing the calcium and magnesium ions of hard water with sodium ions, which do not precipitate like calcium ions, to clog tubes and pipes. They also do not form the sticky scum with soaps and detergent and hence makes washing less troublesome. Now let's have a look at how do water softeners work?
