Introduction
The hypothesis is the balloon will be bigger and bigger with the increase of vinegar.
The chemical reaction between the baking soda and vinegar produces bubbles of carbon dioxide gas as part of this acid-base reaction.
Sodium hydrogen carbonate (baking soda) reacts with ethanoic acid found in vinegar in a 1:1 ratio in the following reaction: baking soda (sodium bicarbonate) + vinegar (acetic acid) --> carbon dioxide + water + sodium ion + acetate ion
HC2H3O2 (aq) + NaHCO3 (s) → H2O (l) + CO2 (g) + NaC2H3O2 (aq) …show more content…
Carbon dioxide is responsible for the fizzing and bubbling of this potion. It is also the gas that forms bubbles in carbonated beverages, like sodas.
A pair of glasses, a funnel, lab coat, teaspoon, 4 medium-sized balloons, baking soda, permanent marker, vinegar and 4 plastic 500 ml bottles are needed.
Procedure
Step 1: Put on glasses and lab coat.
Step 2: Stretch balloons several times to ensure they are flexible, without any holes.
Step 3: Use the permanent marker, label the 4 bottles: 1, 4, 7, 10
Step 4: Use the funnel, add 1 level teaspoon of baking soda to each
