Explain What Happened When I Poured Vinegar And Baking Soda Experiment

I performed the vinegar and baking soda experiment. The first thing that happened when I poured vinegar on top of the baking soda was an overflow of fizz and bubbles. These bubbles were the carbon dioxide escaping from the solution. White foam overflowed over the rim of the container. I felt the cup dropping temperature slightly as the reaction took place. The temperature dropped about 6 degrees Celsius. The remaining solution was a filmy and diluted. The result was sodium acetate dissolved in water. This reaction was a double displacement reaction. The sodium bicarbonate reacted with the acetic acid vinegar and produced sodium acetate, water, and carbon dioxide. The carbon dioxide escaped from the solution leaving water and sodium acetate.
