This salt is formed from the Na+ ion and the carbonate ion. However, because Na+ reacts with water to form a strong base (NaOH) there is no reaction for that species because it dissociates completely. When the carbonate ion reacts with water, its negative 2 charge causes its protonation as it accepts the proton from water forming bicarbonate and hydroxide ions. Therefore the hydrolysis reaction for the salt ignoring the inert species is
CO3(2-) + H2O ⇌ HCO3(-) + OH(-)
This is a basic salt because it produces hydroxide ions. When dissolved in water this salt would cause an increase in the pH.
Na2CO3
write the hydrolysis reaction for the salts. Dissociate the salt into cation and anion and ignore inert species
