Interpretation: Whether conjugate acid with low
Concept introduction: According to the Bronsted-Lowry concept, the substance that donates proton is termed as acid while that accepts or gains protons is called a base. Species formed after loss of protons from acids are known as their respective conjugate bases whereas conjugate acid is produced by the addition of protons to base. The strength of an acid is determined by its
According to Lewis's concept, the substance that donates electron pair is termed as a base while that accepts or gains electron pair is called acid. For example,
According to the Arrhenius concept, substances that donate hydrogen ions in solutions are known as acids while bases are substances that release hydroxide ions in solutions.
