WebMay 28, 2013 · 6 I need to make a saturated solution of N a X 2 C O X 3 and according to the available data I should add 22 g in 100 ml of water at 25 ∘ C. I wanted to make 300 ml solution, which would require 66 g. But, even after adding 110 g of the salt, no turbidity appears which might indicate saturation. WebThe titration involved in the determination of the carbonate content is an example of a weak base being titrated with a strong acid. The two weak bases involved are CO2 − 3 with Kb1 = 2.1 × 104 and HCO − 3 with Kb2 = 2.4 × 10 − 8. The reactions involved are: CO2 − 3 + H3O + ⇌ HCO − 3 + H2O. and. tech mahindra us address
