Sahay Sir > Question Answers > N Awasthi Physical Chemistry > Chapter 6 - Ionic Equilibrium (Level 1 and Level 2) > The pH of a solution containing 0.4 M HCO−3 and 0.2 M CO2−3 is : [Ka1(H2CO3) = 4×10^−7, Ka2(HCO^−3) = 4 × 10^−11]

The pH of a solution containing 0.4 M HCO−3 and 0.2 M CO2−3 is : [Ka1(H2CO3) = 4×10^−7, Ka2(HCO^−3) = 4 × 10^−11]

Ka2(HCO^−3) = 4 × 10^−11] The pH of a solution containing 0.4 M HCO−3 and 0.2 M CO2−3 is : [Ka1(H2CO3) = 4×10^−7
