Homework Statement
A student prepares two solutions:
Solution A is prepared by mixing 50cm3 of 0.100mol dm-3 CH3COOH(aq) with 25cm3 of 0.100mol dm-3 NaOH(aq)
Solution B is prepared by mixing 25cm3 of 0.200mol dm-3 CH3COOH(aq) with 50cm3 of 0.100mol dm-3 NaOH(aq)
Explain why solution A is a buffer solution, but solution B is not.
Homework Equations
None
The Attempt at a Solution
I believe it is because of the reaction
CH3COOH(aq) + NaOH(aq) ↔ CH3COONa(aq) + H2O(aq)
In solution A, the reacants are in the same proportion (concentration wise) as the stoichiometric constants ij the equation, but in solution B the concentrations are in the ratuo 2:1.
