According to the lab introduction in your laboratory manual, the equation for sodium
carbonate dissolving in water is:
3
Na2CO3 + 2H20 – 2Na+ + 2OH- + H2CO3
When this process occurs, sodium carbonate does not 100% separate into ions.
There is always some sodium carbonate in solution.
Based on this reaction, explain whether Sample A or Sample B is most alkaline and
why.
