Questions and Answers

What is a conjugate acid according to the Brønsted–Lowry theory?

A conjugate acid is a chemical compound formed when an acid donates a proton to a base, resulting in the base gaining a hydrogen ion.

What is a conjugate base and how is it formed?

A conjugate base is what remains after an acid has donated a proton during a chemical reaction. It is formed by the removal of a proton from an acid.

Can the conjugate base of an acid itself be acidic? If so, why?

Yes, the conjugate base of an acid may itself be acidic because some acids can give multiple protons.

What is a proton and how is it represented?

A proton is a subatomic particle in the nucleus with a unit positive electrical charge. It is represented as H+. Signup and view all the answers

According to the Brønsted–Lowry theory, what defines an acid and a base?

According to the Brønsted–Lowry theory, any compound that can donate a proton to another compound is an acid, and the compound that receives the proton is a base. Signup and view all the answers

Study Notes

Acids and Bases (Brønsted–Lowry Theory)

A conjugate acid is a species formed when a base accepts a proton (H+).
A conjugate base is a species formed when an acid donates a proton (H+).
A conjugate base of an acid can itself be acidic if it can still donate a proton.
A proton is a hydrogen ion (H+) and is represented by the symbol H+.
According to the Brønsted–Lowry theory, an acid is a species that donates a proton (H+), while a base is a species that accepts a proton (H+).

Adolescence

Adolescence is a transitional period of physical and psychological development between childhood and adulthood.
Adolescence generally occurs during the second decade of life, approximately between 10-19 years old.
Adolescence is often associated with puberty, but can vary in duration and timing.
Puberty typically begins around 10-14 years old for girls and 12-16 years old for boys.
The World Health Organization defines adolescence as the period between 10-19 years old.
Puberty is a period of rapid physical growth and sexual maturation, characterized by hormonal changes and the development of secondary sex characteristics.
