Other Examples of Chemistry in Everyday Life

Let us now discuss some common examples of chemistry in everyday life which most of us never knew about.

The Expiration Date on Bottled Drinking Water

Have you ever wondered why there is an expiration date on a bottle of drinking water? After all, it is just water, isn’t it? Well, most of us haven’t even noticed that there is, in fact, an expiration date on the bottle. The idea behind instilling an expiration on bottled drinking water is to standardise its packaging quality.

What the actual expiration date signifies is if the expiration date is up, the taste of the water will be different as there is a chance that the chemicals in the packaging material may ruin the quality of the water.

Elements in the Human Body

We all know that our body is about 60% water, but then what composes the rest of it? Carbon, Hydrogen, Nitrogen and Oxygen. These elements compose 96% of the human body. Whereas the rest 4% is composed of about 60 elements. Some of these elements include calcium, phosphorus, potassium and sulphur.

Sunblock and Sunscreen

There are two kinds of rays from the sun which are particularly bad for us, UV-A and UV-B. A sunscreen’s action, as the name suggests, functions as a screen and offers protection from sunburn which is caused by UV-B. Whereas, a sunblock has more of reflective nature and blocks both UV-A and UV-B radiations.
