What is correcr Kb expression for base CO32-
[CO3}2- + HOH ==> H^+ + [HCO3]^-
Kb1 = [H^+][HCO3]^-/[CO3^]2-
The correct chemical formula for the carbonate ion is CO3^2-. However, I believe you are asking about the expression for the base dissociation constant (Kb) of the carbonate ion. The Kb expression for CO3^2- is as follows:
CO3^2- + H2O ⇌ HCO3^- + OH^-
In this expression, CO3^2- acts as a base by accepting a proton (H+) from water, resulting in the formation of the bicarbonate ion (HCO3^-) and hydroxide ion (OH^-). The Kb expression quantifies the equilibrium constant for this reaction.
The correct chemical formula for carbonate ion is CO3^2-.
To obtain the Kb expression for the carbonate ion, we need to consider the equilibrium reaction that occurs when it reacts with water:
CO3^2- + H2O ⇌ HCO3- + OH-
The Kb expression represents the equilibrium constant for the reaction of carbonate ion with water, specifically the dissociation of HCO3- and OH-.
Kb = [HCO3-][OH-] / [CO3^2-]
Here, the square brackets [ ] denote the concentration of each species involved in the reaction. Therefore, the Kb expression will depend on the concentrations of HCO3- and OH- ions, as well as the concentration of CO3^2-.
