Calcium Chloride Properties and Reactions

The video explores whether calcium chloride (CaCl2) is acidic, basic, or neutral when dissolved in water. It explains that CaCl2 is formed from a neutralization reaction between calcium hydroxide, a strong base, and hydrochloric acid, a strong acid. As a result, the solution of CaCl2 in water is neutral with a pH of 7. Dr. B concludes that CaCl2 in water is neutral due to its formation from a strong acid and a strong base.
