... b) The initial conductivity is high because of the presence of Ba2+ and OH– ions. The conductivity decreases because Ba2+ forms insoluble BaSO4 with the addition of SO42–. The conductivity also decreases because OH– combines with the addition of H+ ions by forming H2O. Beyond the equivalence point c ...
