What is a simple definition of an acid?

An acid is any substance that in water solution tastes sour, changes blue litmus paper to red, reacts with some metals to liberate hydrogen, reacts with bases to form salts, and promotes chemical reactions (acid catalysis).

What is an acid and what is a base?

An acid is a substance that donates protons (in the Brønsted-Lowry definition) or accepts a pair of valence electrons to form a bond (in the Lewis definition). A base is a substance that can accept protons or donate a pair of valence electrons to form a bond. Bases can be thought of as the chemical opposite of acids.

What are acids short 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.

What is an alkali in chemistry?

alkali, any of the soluble hydroxides of the alkali metals—i.e., lithium, sodium, potassium, rubidium, and cesium. Alkalies are strong bases that turn litmus paper from red to blue; they react with acids to yield neutral salts; and they are caustic and in concentrated form are corrosive to organic tissues.

What is the meaning of acid for kids?

What is an acid Class 10?

Acids: Acids are sour in taste, turn blue litmus red, and dissolve in water to release H+ ions. Example: Sulphuric acid (H2SO4), Acetic Acid (CH3COOH), Nitric Acid (HNO3) etc. Properties of Acids: Acids have a sour taste.

Is water a base?

Pure water is neither acidic or basic; it is neutral.

How do you explain acid and base to a child?

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.

What is an alkali answer?

An alkali can also be defined as a base that dissolves in water. A solution of a soluble base has a pH greater than 7.0. The adjective alkaline is commonly, and alkalescent less often, used in English as a synonym for basic, especially for bases soluble in water.

What is an acid and an alkali?

Acids and Alkalis. Acids are a group of chemicals that contain a H= ion example’s of which are vinegar, Hydrochloric acid and Sulphuric acid. Alkalis are a group of chemicals that contain the OH= ion and have a soapy feel. An example is Sodium Hydroxide. In solid form they are called bases and in solution alkalis.

What is an acid and a base KIDS definition?

Acids and bases are two special kinds of chemicals. Whether a liquid is an acid or base depends on the type of ions in it. If it has a lot of hydrogen ions, then it is an acid. If it has a lot of hydroxide ions, then it is a base.
