This document investigates the chemical reaction that occurs when mixing sodium bicarbonate (NaHCO3), calcium chloride (CaCl2), and phenol red. Evidence will be presented to support the claims that this reaction produces a noticeable chemical change, is exothermic, and adheres to the law of conservation of mass. Initial observations of the reactants and detailed observations during and after the reaction will also be recorded to provide a thorough understanding of the chemical processes involved.
