Elaborate The Concepts Of Acids

The article contains a brief explanation about acids, their characteristics, and examples, along with a description of folic and salicylic acids

Meaning of acids

When the term acid comes to mind, many people perceive it as a dangerous substance that can burn them or cause severe harm to their bodies, but that is not completely true. Acids are substances in nature that have specific characteristics, mostly contrasting to that of bases, and mild acids don’t harm humans or other creatures. 

Observing the environment around them will find that acids are as much a part of their daily life as any other substance. It is used for skincare plant fertilizers as well, as it is present in many foods, such as lemons. Certain kinds of acids can burn or irritate the skin as well. Hence, a person should know about acids as much as they can so that it would be easy to determine between friendly and harmful ones.

Acid is a substance that reacts with bases to form salts, dissolves in water, and has a typical sour taste. All these terms, such as a sour taste or reaction with bases, are applicable in most cases but might have a few exceptions.

Basic Characteristics of acids

Acids are very common in everyone’s life and can be identified easily as they have certain typical properties and ways of reaction, which is applicable in most cases. The basic characteristics of acids are discussed below.

  • Acids are the kind of substance that accept electrons and donate hydrogen, which is exactly the opposite of what gases do.
  • The pH value of acids ranges between 0 to 7 on a pH scale. The pH scale is a method to measure the acidic levels of a substance in which lower the number and lower would be the acidic value, and higher the number, the higher the acidic value.
  • Acids are sour because of hydrogen ions in them, which provides a sour taste. Avoid tasting these as acids with higher pH values can damage the body. There are some foods that people consume daily and are acidic, such as lemons, but they have a low pH value of 3, which makes them safe to consume.
  • Whenever acids react with metals, it produces hydrogen gas, a signature mark of a substance being acid.
  • One of the most basic ways to understand the property of a substance is a litmus paper test. If a substance is acidic, it will change the blue litmus paper into red and won’t change color when experimented with red litmus paper.

Salicylic Acid

Salicylic acid is a plant occurring substance with a strong bitter taste and is prominently used for various purposes. It comes under the category of organic compounds. The most significant use of salicylic acids these days is for the skin. It is known to avoid any kind of inflammation on the skin when used in very low proportion and removes the dead skin from the surface, giving room for the growth of a fresh layer. It avoids any kind of clogging in pores and is a skin friendly substance. One should always keep in mind that it only suits the outer skin and should not be consumed.

Another important usage of salicylic acid is that it is used in the production of aspirin and other medicinal products. It is also used in different food preservatives but never consumed directly.

Folic Acid

Folic acid is a substance that plays a very important role in the human body. It is present in the body in required proportion, but in many cases, it is deficient in the body. It can cause severe issues such as anaemia which is a very common disease in women during their menstrual process. Not just a normal one, but many times people suffer from a specific kind of anaemia, which is totally caused by folate deficiency. 

Folate is also known as vitamin B-9, which is a type of vitamin B . Women are given various types of supplements containing folic acid because its deficiency can cause complications during pregnancy. It can also cause depression in people and lead to a constant feeling of fatigue and weakness. One of the major reasons behind the consumption of folic acid is the need for a generous amount of folic acid for child development. It is essential for child growth in its early stages, and it is known that folic acid during pregnancy reduces the chances for the child to suffer from autism. There are various kinds of foods with ample amounts of folic acids, such as kidney beans, orange juice, broccoli, asparagus, etc.

Conclusion

Acids are substances that are sour in taste and possess certain properties, which are mostly in contrast with baes. It has a value of 0 to 7 and is safe to consume or use or apply depending on the type of acid it is and its pH value. It should always be kept in mind that acids are necessary for life as much as any other substance, but one should use them only after getting to know their pros and cons.
