Problem- 1) If you add 3.4 grams of sodium acetate to 50 mL of Vinegar what type of solution would you get? Does this solution change its pH greatly with the addition of a few drops of strong acid? If you add a few drops of strong acid to pure water would it's pH change by more or less than the above situation?
2) Write the chemical equation showing the equilibrium that is present in vinegar explains what happens when you add sodium acetate to vinegar.
