Some P-Block Elements

- Let's look at various discoveries and applications of this chapter.
1
Boric Acid: A Multifaceted Compound
Boric acid has a broad range of uses. We can find its involvement in many spheres from antiseptics to industrial and nuclear power plants. Boric acid is a naturally occurring compound and is made up of boron, hydrogen and oxygen. Let's take a look at its uses.

Acts as a magic in carrom boards: It is used as a lubricant on carrom board and makes the board smooth to play on.

In nuclear power plants:
Boric acid has a tendency to absorb neutrons and therefore, is used as a neutron poison to reduce the probability of thermal fission.
In Industries:
Boric acid is used in industries for the manufacture of fiberglass and LCD displays.
Apart from all the above uses, it is used as an insecticide to prevent infestation by insects such as cockroaches. It can be used in agriculture for the treatment of boron deficiency in plants.

Lead: An Integral Part of Our Lives
Lead being a toxic metal is an integral part of our lives.
The lead metal is not very expensive and therefore, is used in batteries at homes.

Chemistry Behind the Making of Slime
Slime is a soft viscous mud that is unpleasant to touch. But these days it is prepared artificially and comes in many different colours and looks attractive. Kids like this very much and they love to play with it.
Do you also get attracted towards the colourful slime? If yes, then let's find out the chemistry behind it.

The colourful slimes are made from a combination of polyvinyl acetate, polyvinyl alcohol and borax(laundry detergent which contains borax).
The tetraborate ions form cross links between PVA polymers and creates a three dimensional network that traps water resulting in a semi solid gel.

The bonds present in slime are strong enough to bind it together, but weak enough for slime to be mouldable.
