I for iron

This is the ninth in the series of 26 posts this month, one post a day, barring four Sundays, each on a theme corresponding to a letter of the English alphabet. My theme this year is "Chemicals in our life", spurred by my interest in chemistry.

It is one of the most abundant elements in the universe, and it makes up most of the Earth's core and crust. 

Iron has the symbol Fe (Ferrum in Latin) and the atomic number 26. Iron has a high melting point of 1,538°C (2,800.4°F) and a boiling point of 2,862°C (5,181.8°F). 

Iron is a lustrous, silvery-grey metal that is magnetic. 

In its pure form, iron is actually soft and ductile.

Most of the iron we see is hard because it's alloyed or mixed with other metals.

Some common iron alloys are steel (iron with carbon), stainless steel (iron with chromium and nickel), cast iron (iron with carbon and silicon), and wrought iron (iron with very low carbon).

Needless to say, iron is widely used as a material for tools, weapons, machines, buildings, bridges, railways, cars, ships, and many other applications. 

Iron is important for our health. It's a component of haemoglobin, the protein that carries oxygen in red blood cells. Iron deficiency can cause anaemia, a condition that reduces the oxygen-carrying capacity of the blood. 

Iron is also involved in many metabolic processes and enzyme reactions in the body. 

It is often alloyed with other metals to improve its strength, hardness, corrosion resistance, or magnetic properties.

H for Hydrogen peroxide

This is the eighth in the series of 26 posts this month, one post a day, barring four Sundays, each on a theme corresponding to a letter of the English alphabet. My theme this year is "Chemicals in our life", spurred by my interest in chemistry.

Hydrogen peroxide is one of the chemicals that I have been familiar with right from childhood. 

My father was a chemistry teacher (that's one main reason for my interest in chemistry), and at home, we had a bottle of diluted hydrogen peroxide as a disinfectant.

It is a compound which contains two hydrogen atoms and two oxygen atoms and has a chemical formula of H2O2.  

It's a pale blue liquid at room temperature and is slightly more viscous than water. It boils at 150 degrees C (302 degrees F)

It is important to note that hydrogen peroxide is a toxic chemical and should be used with caution.

It can cause skin irritation and burns if not diluted properly. 

It has wide applications in our daily life. But most of its applications are in a diluted form. How much it has to be diluted depends on where and how it's used. 

Hydrogen peroxide is used as a disinfectant in the medical industry, food industry, and laboratory settings. 

In the food industry, hydrogen peroxide is used to kill bacteria, viruses, and fungi from food processing equipment and surfaces. 

It is also used in the production of cheese and other dairy products to prevent the growth of bacteria.

Hydrogen peroxide has industrial applications as well, for example, in the production of paper and textiles. 

In the paper industry, it's used to bleach and brighten paper products. 

It's used in the production of cotton and wool to remove impurities and enhance the appearance of the material. 

In the personal care industry also, hydrogen peroxide is used, for bleaching hair and teeth, besides in the treatment of skin inflammation. 

Hydrogen peroxide is a poisonous chemical, and ingesting it can lead to stomach pain, vomiting, and even death. 

So, it is essential to store and handle hydrogen peroxide properly under professional supervision to avoid any accidents or harm.

G for Gallium

This is the seventh in the series of 26 posts this month, one post a day, barring four Sundays, each on a theme corresponding to a letter of the English alphabet. My theme this year is "Chemicals in our life", spurred by my interest in chemistry.

We might not get to hear much about this element, but it's there everywhere, sort of, in this age of electronics and the internet.

We will come to that soon.

Before that, a little bit about Gallium, the element itself. 

It has the atomic number 31 and was discovered in 1875 by French chemist Paul-Émile Lecoq de Boisbaudran, who named it after Gallia, the Latin name for France.

Gallium has a silvery-blue appearance and is soft enough to be cut with a knife. 

It has a very low melting point of about 29.8 degrees C (85.6 degrees F), which means it can melt in your hand or on a hot day.

It is one of the few metals that can exist as a liquid at room temperature. 

Its boiling point is 2,204 degrees C (3,999.2 degrees F)

Gallium has many uses in various fields, especially in electronics and optics. 

About 95% of all gallium is used to make gallium arsenide (GaAs), which is used in blue-ray technology, blue and green LEDs, mobile phones, solar cells, lasers, and microwave devices.

Gallium is also used to make other compounds, such as gallium nitride (GaN), gallium phosphide (GaP), and gallium antimonide (GaSb), which have applications in optoelectronics, semiconductors, and thermoelectric devices. 

Gallium can also alloy with other metals, such as aluminium, copper, and zinc, to improve their properties.
