does it take more or less base to neutralize vinegar with baking soda than lemon juice

It would generally require more baking soda to neutralize vinegar compared to lemon juice. This is because vinegar is an acid, specifically acetic acid, while lemon juice contains citric acid. Acetic acid has a higher concentration of hydrogen ions (H+) compared to citric acid. Therefore, a larger amount of base (baking soda) is needed to neutralize the higher acidity of vinegar compared to lemon juice.
