Question

what are the acids ?​

Answer 1

$\star\;\;{\underline{\underline{\frak \pink{Acid:-}}}}$

• Acid are the substance which gives Hydrogen ions in Solution. Acids are sour in taste.

For example:- Sulphuric acid $\sf H_2 SO_4$) , Hydrochloric acid (HCl) etc.

• Acids converts blue litmus into red litmus, and the red litmus remains red in acidic Solution.

• An acid is a proton donor.

• Acids are molecules or ions capable of coordinating with unshared electron pairs.

${\underline{\underline{\sf{\purple{\dag\; Properties\;of\;acid:-}}}}}$

• Thier pH value are less than 7.

• They are good conductor of electricity.

• They produce hydrogen gas when reacts with metals.

• They are corrosive in nature.

Answer 2

ᴀɴsᴡᴇʀ:-

An acid is a molecule or ion capable of donating a proton, or, alternatively, capable of forming a covalent bond with an electron pair. The first category of acids are the proton donors, or Brønsted–Lowry acids.

The first category of acids are the proton donors, or Brønsted–Lowry acids. In the special case of aqueous solutions, proton donors form the hydronium ion H3O+ and are known as Arrhenius acids. Brønsted and Lowry generalized the Arrhenius theory to include non-aqueous solvents. A Brønsted or Arrhenius acid usually contains a hydrogen atom bonded to a chemical structure that is still energetically favorable after loss of H+.

A Brønsted or Arrhenius acid usually contains a hydrogen atom bonded to a chemical structure that is still energetically favorable after loss of H+.Aqueous Arrhenius acids have characteristic properties which provide a practical description of an acid.[2] Acids form aqueous solutions with a sour taste, can turn blue litmus red, and react with bases and certain metals (like calcium) to form salts. The word acid is derived from the Latin acidus/acēre, meaning 'sour'.[3] An aqueous solution of an acid has a pH less than 7 and is colloquially also referred to as "acid" (as in "dissolved in acid"), while the strict definition refers only to the solute.[1] A lower pH means a higher acidity, and thus a higher concentration of positive hydrogen ions in the solution. Chemicals or substances having the property of an acid are said to be acidic.
