ACIDS AND BASES: PROTON DONORS AND ACCEPTORS Bronsted-Lowry Theory is also called "Proton Theory" of acids and bases. This theory was introduced independently in 1923 by the Danish chemist Johannes Nicolaus Bronsted and the English chemist Thomas Martin Lowry. Bronsted-Lowry Theory states that any compound that can transfer a proton to any other compound is an acid, and the compound that accepts the proton is a base. In other words, it is based on the compounds abilities to either donate or accept protons. A Bronsted-Lowry acid is proton (hydrogen-ion) donor and a Bronsted-Lowry base is a proton (hydrogen ion) acceptor. A strong acid dissociates almost completely into a proton and a weak conjugate base, while a strong base ionizes entirely, releasing OH- ion, which is a powerful proton acceptor. Expound these: "Many biological molecules are weak acids or weak bases." "The stronger the acid, the weaker its conjugate base."

Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
Bronsted Lowry Base In Inorganic Chemistry
Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.
Question
(PLEASE TYPE YOUR ANSWER)
Transcribed Image Text:ACIDS AND BASES: PROTON DONORS AND ACCEPTORS
Bronsted-Lowry Theory is also called Proton Theory" of acids and bases. This theory was introduced
independently in 1923 by the Danish chemist Johannes Nicolaus Bronsted and the English chemist Thomas
Martin Lowry. Bronsted-Lowry Theory states that any compound that can transfer a proton to any other
compound is an acid, and the compound that accepts the proton is a base. In other words, it is based on the
compounds abilities to either donate or accept protons. A Bronsted-Lowry acid is proton (hydrogen-ion) donor
and a Bronsted-Lowry base is a proton (hydrogen ion) acceptor.
A strong acid dissociates almost completely into a proton and a weak conjugate base, while a strong
base ionizes entirely, releasing OH- ion, which is a powerful proton acceptor.
Expound these:
"Many biological molecules are weak acids or
weak bases."
"The stronger the acid, the weaker its conjugate
base."
