Results and Discussion: This experiment included performing many different chemical reactions and each reaction was made into a balanced chemical equation. A1: Barium chloride was reacted with magnesium sulfate to produce barium sulfate, turning the solution from clear to milky white. This reaction is an example of a precipitation reaction. Chemical Equation: MgSO + BaCl BaSO + MgCl A2: HCl was added to sodium carbonate. The products included water, and NaCl. Carbon dioxide was also produced because when the HCl was added, the solution bubbled. Chemical Equation: Na CO + HCl NaCl + H O + CO A3: Acetic acid and sodium hydroxide were reacted to form water and sodium acetate. The molarity of the acetic acid was 0.150 M. The molarity of the sodium hydroxide was unknown, and had to be found. To determine this, two minititrations were performed using a phenolphthalein indicator. In a test tube filled with 10 drops of acetic acid and 2 drops in indicator, drops of sodium hydroxide were added until the indicator turned pink. It took 16 drops until all the H
