To explore chemical reactions, we mixed small amounts of 4 different substances in zip-lock baggies. The substances we used were the compounds Sodium bicarbonate (Baking soda) NaHCO3, Calcium chloride CaCl2, Water H2o, and the mixture Phenol red. Three of the indicators of a chemical reaction are: a change of color, a change of temperature, or a gas is produced.
When we mixed the CaCl2 + Phenol red, the color changed to magenta, the temperature got hotter, and there was no gas produced. When we mixed CaCl2 + H2O, there was no color change, the temperature got hotter, and there was no gas produced. When we mixed the CaCl2 + NaHCO3 + H2O, the color changed to pink, the temperature first got warm and then cooled off, and there was a gas produced
