What is ph of calcium hydroxide?

The pH of calcium hydroxide, also known as slaked lime or hydrated lime, is approximately 12.4. This high pH is due to the strong basic nature of the compound, which makes it useful for a variety of purposes, such as water treatment, construction, and agriculture. When added to water, calcium hydroxide dissociates into calcium ions and hydroxide ions, which raise the pH of the solution. However, it is important to handle calcium hydroxide with care as it can cause skin and eye irritation and can be harmful if ingested or inhaled in large amounts.
