Lime water

Uses of Lime water

Acid-base titrations:

Lime water can be used as a standardized solution in titrations to determine the concentration of acids. It’s often used to titrate solutions containing weak acids because calcium hydroxide reacts with them to form calcium salts and water.

Carbon dioxide detection:

Lime water turns milky when exposed to carbon dioxide due to the formation of calcium carbonate, which is insoluble in water. This property is often used to detect the presence of carbon dioxide in gases.

Water treatment:

Lime water is used in water treatment processes to raise the pH of acidic water, helping to neutralize acidity and reduce corrosion of pipes and equipment. It also facilitates the precipitation of impurities and contaminants.

Soil pH testing:

Lime water can be used in soil testing to determine soil pH. By adding lime water to a soil sample, the reaction with any acidic components in the soil can indicate the acidity level of the soil.

Precipitation reactions:

Lime water is often used in precipitation reactions in chemistry experiments. Its reaction with various substances can lead to the formation of precipitates, which can be studied for analytical or educational purposes.

Hydrolysis reactions:

Lime water can undergo hydrolysis reactions with certain compounds, which can be studied to understand the behavior of these compounds in aqueous solutions.
