Under what soil condition do you think a farmer would treat the soil of his fields with quick lime (calcium oxide) or slaked lime (calcium hydroxide) or chalk ( calclum carbonate)?

Text Solution

AI Generated Solution

To determine the soil conditions under which a farmer would treat the soil with quick lime (calcium oxide), slaked lime (calcium hydroxide), or chalk (calcium carbonate), we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Nature of the Soil**: - The first step is to understand the pH level of the soil. Soil can be classified as acidic, neutral, or alkaline based on its pH value. - Acidic soil has a pH value less than 7. ...

Solid calcium oxide reacts vigorously with water to form calcium hydroxide accompanied by liberation of heat. This process is called slaking of lime. Calcium hydroxide dissolves in water to form its solution called lime water. Which among the following are true about slaking of lime and the solution formed? (i) It is an endothermic reaction. (ii) It is exothermic reation. (iii) The pH of the resulting solution will be more than seven. (iv) The pH of the resulting solution will be less than seven.

Limestone is a naturally occuring form of calcium carbonate. It is used as building materials and also for manufacture of other building materials such as portland cement. It is used for the production of quickline and slaked lime which have wide applications in chemical, metallugical and construction industry. The pure CaCO_(3) , called precipitated calcium carbonate, is used extensively as filler, providing bulk to materials such as paint, plastics, printing links and rubber. it is also used in toothpastes, cosmetics and antacids. Quicklime and slaked lime are the cheapest and the most widely used bases for neutralising unwanted acids. Lime is used to neutralise acidic soils. An important application of quicklime is in air pollution control for the removal of SO_(2) in electric power plants. slaked lime is used in the manufature of other alkalis and bleacing powder, in sugar refinig, in tanning hide and in water softening. Quicklime is used in electric power plants with carbon to check pollution. What product of calcium is formed?
