Slaked lime, also known as calcium hydroxide, helps neutralize acidity in soil by increasing the soil's pH level. It reacts with acidic compounds in the soil to form water and a neutralized salt. This process helps improve soil structure and makes essential nutrients more available to plants.

How can slaked lime be used by farmers and environmentalists?
Farmers use slaked lime as a soil amendment to raise pH levels and reduce acidity in the soil, improving nutrient availability for plant growth. Environmentalists use slaked lime to treat acidic mine drainage and neutralize soil pH in areas affected by acid rain, helping to restore damaged ecosystems and improve water quality.
What happens when slaked lime react with chlorine?
When slaked lime (calcium hydroxide) reacts with chlorine gas, calcium hypochlorite and calcium chloride are formed. This reaction is commonly used in water treatment processes to generate hypochlorous acid, which is a disinfectant to kill bacteria and other microorganisms.
What is the common name for calcium hydroxide solution?
The common name for calcium hydroxide solution is lime water.
What does calcium oxide produce when it reacts with water?
calcium oxide (quick lime) produces calcium hydroxide (slaked lime) when reacts with water.
What do farmers put on acidic soil?
Farmers can add lime to acidic soil to help raise its pH level and make it more suitable for growing crops. Lime helps to neutralize the acidity in the soil, making it easier for plants to absorb essential nutrients. It's important to test the soil first to determine the amount of lime needed for effective neutralization.
What is the nature of the aqueous solution of slaked lime?
The aqueous solution of slaked lime, or calcium hydroxide, is basic in nature. It can react with acidic substances to form salts and water. Slaked lime is often used to neutralize acidic soils or in water treatment to remove impurities.
What substance is added to acidic soil?
Adding lime to acidic soil can help raise pH levels by neutralizing the acidity. Lime is typically applied in the form of ground limestone or dolomite, and helps to improve soil structure and nutrient availability for plants.
Why do Farmers Use Slaked Lime For Animal Pens?
Farmers use slaked lime in animal pens to help control odors, reduce moisture levels, and sanitize the environment. It can also help to neutralize acidic conditions caused by animal waste, creating a more comfortable and healthier living space for the animals.
Why farmers add slaked lime to acidic soils?
Calcium Hydroxide (or Slaked Lime) is a strong base (as are all metal hydroxides, oxides, and carbonates) A Base is a substance with a pH of 8 or more. When an acid and a base react, the result is that a salt and water is formed. This also has the effect of neutralising a substance (giving it a pH of 7 or closer to 7) So slaked lime is added in order to reduce the acidity of the soil
Why do farmers sometimes add slaked lime to acidic soil?
Farmers add slaked lime to acidic soil to raise the pH level, making the soil less acidic and more suitable for optimal plant growth. This helps improve nutrient availability to plants, enhances soil structure, and fosters beneficial microbial activity.
How is slaked lime made from quicklime?
slaked lime is made by adding water to quicklime.
Explain the advantages of using slaked lime instead of powdered limestone for neutralising acidic soil?
Slaked lime is much more alkaline and effective at reducing acidity quickly - it is Ca(OH)2 whereas powdered limestone is CaCO3 and not as alkaline/basic. CO2 is also given off when the limestone reacts with the acid. Water is given of when slaked lime reacts. Mathematically it takes 100 g of limestone to 73g of HCl (as an example) where it would take only 74g of slaked lime per 73g HCl.
What is slaked lime chemical name?
Slaked lime is Calcium Hydroxide - Ca(OH)2
What will happen when dry slaked lime react with chlorine?
When dry slaked lime reacts with chlorine gas, it forms calcium chloride, calcium hypochlorite, and water. This reaction is commonly used in water treatment processes to disinfect and purify water, as calcium hypochlorite is a powerful disinfectant.
What are the differences between hydrated lime and slaked lime, and how do they compare in terms of their properties and uses?
Hydrated lime and slaked lime are both forms of calcium hydroxide, but they differ in how they are produced. Hydrated lime is made by adding water to quicklime, while slaked lime is made by adding water to lime putty. In terms of properties, hydrated lime is a dry powder that is more stable and easier to handle, while slaked lime is a wet paste that is less stable and can harden over time. Hydrated lime is commonly used in construction, agriculture, and water treatment, while slaked lime is often used in traditional building materials and as a chemical reagent. Overall, hydrated lime is more versatile and widely used compared to slaked lime due to its easier handling and broader range of applications.
How is slaked lime used?
Slaked lime, properly called calcium hydroxide, has a tremendous number of uses. It is the main ingredient in whitewash, it is used in making paper, it's used in treating sewage, it's in commercial hair removal creams, and it's used in pesticides and brake pads.
How can slaked lime be used by farmers and environmentalists?
Farmers use slaked lime as a soil amendment to raise pH levels and reduce acidity in the soil, improving nutrient availability for plant growth. Environmentalists use slaked lime to treat acidic mine drainage and neutralize soil pH in areas affected by acid rain, helping to restore damaged ecosystems and improve water quality.
