Question

Calculate the concentration of all the species present in a 0.100 M Na2CO3 solution, considering the following equilibria.

H2O + CO32– ⇋⇋ HCO3– + OH–     Kb1 = 2.1×10×10–4

HCO3– + H2O ⇋⇋ H2CO3 + OH–     Kb2 = 2.4×10×10–8

[Na+] =  mol dm–3

[CO32–] = mol dm–3 

[HCO3–] =  mol dm–3

[H2CO3] = mol dm–3
