what is a acid !!! for what will we use
Answers
Answer:
An acid is a chemical substance, usually a liquid, which contains hydrogen and can react with other substances to form salts. Some acids burn or dissolve other substances that they come into contact with.
Explanation:
A substance is acidic if it has a pH level of 0 through 7, where 0 is the most acidic. A substance is basic, then, if it has a pH level of 7 through 14, where 14 is the most basic. If a substance has a pH of exactly 7, it's neutral. This means it has equal amounts of hydrogen and hydroxide ions.
Answer:
This is an ace verified answer-
An acid is a molecule or ion capable of either donating a proton, known as a Brønsted–Lowry acid, or, capable of forming a covalent bond with an electron pair, known as a Lewis acid. The first category of acids are the proton donors, or Brønsted–Lowry acids.
OR
a substance with particular chemical properties including turning litmus red, neutralizing alkalis, and dissolving some metals; typically, a corrosive or sour-tasting liquid of this kind.
OR (chemistry)
a molecule or other species which can donate a proton or accept an electron pair in reactions.
OR (adjective)
adjective
1.
containing acid or having the properties of an acid; having a pH of less than 7.
"acid soils"
2.
sharp-tasting or sour.

Uses of Acids
1. Hydrochloric Acid (HCl)
Dilute hydrochloric acid is used in various industries that use heating applications. It is applied to remove deposits from the inside of the boilers.
Hydrochloric acid is also used for cleaning sinks and sanitary ware.
2. Sulphuric Acid (H2SO4)
Sulphuric acid is such an important industrial chemical that it is called the king of chemicals. Some of its major uses are as follows:
Sulphuric acid is used in car batteries.
It is used in the manufacture of paints, drugs, dyes, and to produce fertilizers.
3. Nitric Acid (HNO3)
It is used by goldsmiths for cleaning gold and silver ornaments.
It is also used for the production of fertilizers such as ammonium nitrate.
4. Acetic Acid (CH3COOH)
Acetic acid is used directly to enhance the flavour of food. In fact, we commonly know acetic acid as vinegar.
It is also used as a cleansing agent in products meant for cleaning windows, floors, utensils, etc.
It also helps to remove stains on woodwork such as furniture and carpets.
Acetic acid is used as a preservative in pickles, etc. Most microorganisms cannot live in an acidic environment. An acidic environment either slows down their activities or can also kill them. This is why you will find vinegar in many commonly packaged food items such as pickles, sauce, ketchups, etc
Subjective - Sulphuric acid is used in car batteries. It is used in the manufacture of paints, drugs, dyes, and to produce fertilizers.
