What is an acid, Type of acid – Acid Kya Hai

Education Science

What is acid called (Acid in Hindi) :: There are many such topics in science. Which are considered very important in every competitive exam. Which Hindivani is gradually providing you detailed information of every topic. Today we have brought the topic. Its name is – what is called acid. These are very important topics of science. Under this topic, what do we call acid? , What is acid rain? Information about the types of acids, acids and their natural sources etc. will be provided. So let’s read.

What is acid?

The substances that are sour and turn blue litmus red are called acids.
When these substances are dissolved in water, they dissociate and give hydrogen ions.
The acids that are obtained from living sources are called organic acids such as acetic acid, citric acid, elemental acid.
The acids that are obtained from unrefined sources are called mineral acids such as hydro chloric acid, nitric acid, sulfuric acid.

Types of Acids –

Acids are divided into four parts. Which are as follows.

Hydroacids – Acids that do not contain oxygen, but in addition to hydrogen are other non-metallic elements. Hydro acids are called.

Such as – hydrochloric acid (HCL), hydrofluoric acid (HF), hydrobromic acid (HBr) etc.

Oxycids – Acids that contain hydrogen and oxygen as well as other elements are called oxy acids.

Eg – sulfuric acid, phosphorus chlorous acid, nitric acid.

Strong acids – acids that are completely ionized in aqueous solutions. They are called strong acids.

Like – HCL

Weak acids – those acids which are partially ionized in aqueous solutions. Weak acids are called.

Such as acetic acid, formic acid, carbonic acid etc.

Properties of acids –
The following are the properties of acids.

Acids are conductors of electricity.
Acidic reacts with more active metals to release hydrogen.
Acids liberate carbon> dioxide gas by reacting with metal carbonates and metal bicarbonates.
Acid reacts with the base to form salts and water.
Acids are corrosive in nature.
Acids are sour in taste.
Acids merge in water. When an acid is dissolved in water. So heat is produced in it. And the temperature of the villian increases. The amount of heat produced depends on the nature of the acid. A large amount of heat is produced when strong acids are dissolved in water. Therefore, they never add water to dilute the strong acid. Instead we mix it slowly in water.

Burning in Acid –

We should always mix slowly in water to dilute the strong acids. Water is not in acids because this reaction is exothermic. Due to which water in acid is spilled and falls out, and can harm us, so it can burn severely due to falling on our clothes or body.

What is acid Rain?

Due to dissolved carbon dioxide in the atmosphere in water in an ordinary year, its pH is generally 5.6, which liberates H + ions in rainwater.

1) When the pH value of rainwater is reduced by 5 due to presence of other acids. So such rain is called acid rain.
2) When sulfur dioxide and nitrogen oxides such as nitrous oxide or nitric oxide dissolve in rainwater in atmospheric air. Let’s make it. Which causes acid rain.
3) Soil acidity of soil increases in acid rain. Due to which the plant and animal world suffer. In acid rain, skin disease asthma remains today, there is a possibility, there is a possibility, there is a possibility, there is a possibility of skin disease asthma today, there is a possibility, there is a possibility of skin disease asthma today, there is a possibility. There is a possibility of skin disease asthma today there is a possibility, there is a possibility of a possibility.

4) Due to soil and water being acidic, there is adverse effect on the produce of animals and flora.

Acids and Their Sources

Acids – Natural Sources

Citric acid – citrus fruits, lemons, orange tomatoes
Acetic acid – in fruit juices, aromatic oils
Lactic acid – milk, yogurt
Formic acid – red ant, burrows, scorpions
Sulfuric Acid – Kashish Oil
Nitric Acid – Sora
Benzic acid – grass leaves and urine
Oxalic acid – Sarel tree
Malic Acid – Apple Banana Orange Peel Potato Carrot
Tartaric Acid – Grape Raw Mango Tamarind
Ascorbic acid – Amla citrus fruits

Uses of Acids

Following are the uses of acids.

Hydro Chloric acid nitric acid and sulfuric acid are considered very important commercially, these are discussed in detail below.

1.Use of hydrochloric acid to make chloride and chlorine gas

  1. To clean the iron sheets before several
  2. To dye textiles in the industry.

Uses of nitric Acid –

  1. Fertilizers to make explosive colors and drugs.

Uses of sulfuric acid –

  1. Fertilizing soda in making plastic synthetic fibers. For refining in petroleum industries
  2. In the lead battery.
