Calcium hydroxide solutions

Calcium hydroxide solution, often called lime water, is a clear liquid made by dissolving calcium hydroxide in water. It has a slightly alkaline (basic) pH and is used in various applications such as neutralizing acids, testing for carbon dioxide (which turns it cloudy), and in agriculture to adjust soil pH. It’s also employed in the food industry and dentistry. Because it’s mildly caustic, handling requires care to avoid skin or eye irritation. Overall, calcium hydroxide solution is an important chemical used in environmental, medical, and industrial processes for its ability to react with acids and other substances.
