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.

Explain why powdered limestone is also used in the chimneys at power stations?
Powdered limestone is used in power station chimneys to remove sulfur dioxide (SO2) from the flue gases produced during combustion. When sulfur dioxide reacts with the limestone, it forms calcium sulfate which can be easily removed, reducing air pollution. This process, known as flue gas desulfurization, helps to comply with environmental regulations and minimize the emission of harmful pollutants into the atmosphere.
Explain how limestone purifies the iron?
When limestone reacts with iron, it removes impurities and forms slag, which is less dense than molten iron and therefore floats over it, allowing it to be tapped off seperatly. It (the slag) is rather useless, but can be used in concrete.

Explain in detail batch and continuous process?
Batch process is a method where a limited quantity of material is processed at a time, which involves filling a tank with raw materials, processing it, and then emptying the tank. Continuous process involves a constant flow of raw materials through a system that is uninterrupted, with outputs being produced continually. Both processes have their own advantages and are used in different industries depending on the requirements of the production.
