* Hydrolysis: CaCl₂ does not undergo hydrolysis, meaning it doesn't react with water to produce hydrogen ions (H+) or hydroxide ions (OH-).
* Strong Acid and Base: CaCl₂ is formed from the reaction of a strong acid (hydrochloric acid, HCl) and a strong base (calcium hydroxide, Ca(OH)₂). The resulting salt is neutral.
Therefore, the pH of a solution of CaCl₂ in water will be close to 7, which is neutral.
Important Note: While CaCl₂ is considered neutral, very concentrated solutions might show a slight acidic tendency due to the hydration of the calcium ions, but this effect is usually negligible.
