In a water solution, how do acids differ from bases?
Acids form salts, but bases do not
Acids turn litmus blue, while bases turn litmus red

Marti took a balloon and filled it with 14 grams of baking soda. She then put 40 mL of vinegar into an empty water bottle. Marti stretched the balloon onto the top of the bottle and recorded the mass. She then flipped the balloon up so the baking soda fell into the vinegar. She observed it bubbling and could hear it fizzing. Marti laughed as the balloon filled with the carbon dioxide that was given off. After the reaction stopped, on the bottom of the bottle, Marti notices a white and clear substance. She remembers that she had learned that when you mix an acid (Vinegar) and a base (baking soda), you create
acid and metal
acid and base
base and water
salt and water
