In this Chemistry video for Class 10 in Hindi we explained three acid-base theories, viz., Arrhenius theory, Brønsted- Lowry theory and Lewis theory. This is a topic of Chapter 2 - 'Acids, Bases and Salts' from NCERT for Class 10.
Arrhenius theory :
Arrhenius acid is a substance that, when added to water, increases the concentration of H+ ions in the water.
Arrhenius base is a substance that, when added to water, increases the concentration of OH− ions in the water.
Brønsted- Lowry theory :
Acid can lose a proton to become its conjugate base.
Base can accept a proton to become its conjugate acid
Lewis theory :
A Lewis acid accepts a pair of electrons from Lewis base.
