1. Write a chemical equation showing why a sodium carbonate solution is basic. Calculate the pH of a 0.10 M sodium carbonate solution, Na2CO3 (aq).
Homework Answers
Sodium carbonate acts as an alkali because when dissolved in water, it dissociates into the weak acid: carbonic acid and the strong alkali: sodium hydroxide.
H20→2H+ +OH-
NaCO3→ Na+ + CO3(2-)
Net reaction:
H2O+NaCO3→H2CO3 + NaOH
