What is chemical purity? If you work in a laboratory or industry dealing with chemicals, it’s essential to understand the term.
Chemical purity is an element containing a single substance and no other elements to tarnish its standalone existence.
The company that creates purity chemicals find the process involving and overwhelming. But it is necessary because professionals can use these chemical products to make medicines, vaccines, and household products.
If you need to learn about chemical purity and everything involved, this is an article for you.
Let’s get started:
Examples of Purity Chemicals
- Iron sulfate
- Calcium carbonate
- Barium nitrate
- Aluminum nitrate
- Silver sulfate
- Potassium hydroxide
- Mercury hydroxide
- Lead oxide
Uses of Pure Chemicals
Chemicals are part of building blocks in the life we live today. So, it is not a surprise that various industries have to use these chemicals in creating essential products and goods. These are end products serving people across the world.
If you are a beginner, pharmaceutical chemicals require these chemicals such as sodium benzoate and sodium chloride. They can use the substances in developing popular drugs helping people relieve pain and aches.
The potent medicines will even help severe battle conditions such as chronic illness. That’s why testing for chemical purity is essential before pharmaceutical companies can use it to develop life-saving medicine.
The food industry, on the other hand, will require chemicals such as sulfates and nitrates. These help to act as preservatives for extending the shelf life of products you find in supermarkets.
In other words, chemical purity is relied upon by many industries for various uses.
Reaching Chemical Purity
Labs should conduct a thorough test to help determine the purity of chemicals. The manufacturer will test the chemical quality through its physical properties. Does it work? Yes, it’s possible because chemicals will react in specific ways after meeting their boiling and melting points. That helps the manufacturer to draw a conclusion of chemical purity.
Concept and Properties
When taking a cup of tea or coffee, you add a cube of sugar. If you look closely at the label, there is a higher chance to find “pure cane sugar.” These are not simple words; “pure” refers to the same thing in the chemical class. It has a specific meaning in the context of chemistry.
In chemistry, a pure substance refers to a substance made of one atom. The measure of a pure substance is referred to as purity. Therefore, pure iron can only have iron atoms. The same case with sugar, it will have sucrose molecules only.
The other thing is that pure substances exhibits defined physical properties. These are properties connected with the ability of the substance to combine with other substances.
The melting point temperatures of pure solids are sharp. And that means melting will occur at a specific temperature. It should be the same with boiling points of liquids to occur at a single temperature. However, other factors such as air pressure will be controlled.
Substances can conduct electricity but are highly affected by purity. That’s because copper, for example, will have efficient conductivity at a pure state. On the other hand, pure liquid water will be a poor electricity conductor because it lacks dissolved electrical conductors.
