The correct answer is NoneKey Points

  •  Alluvial soils: 
    • Alluvial soils are widespread soils in India mostly in Northern Plains and River valleys.
    • These soils cover 40% of the total area of the country. Hence statement a is correct
    • These soils are depositional soils transported and deposited by rivers and streams.
    • Alluvial soils are categorised as Khadar and Bangar based on deposition. Hence statement c is correct.
    • Khadar - New alluvium, deposited by floods annually. 
    • Bangar- old alluvium, deposited away from flood plains.
    • Both Khadar and Bangar contain Calcerous concentration (kankars).
    • Khadar soil is more fertile than Bangar. Hence option d is correct.
    • Alluvial soils are fertile soils. Their nature various from sandy, loam to clay. Hence statement b is correct.
    • Alluvial soils contain an adequate amount of Potash, phosphoric acid and lime. Hence statement e is correct.
    • These soils are intensively cultivated. They are suitable for the cultivation of Sugarcane, paddy, wheat and pulses. Hence statement f is correct.
    • Alluvial soil colour varies from light grey to ash grey.

In a batch process, the reaction takes place in the presence of an acid medium. The acid is drained from the reaction vessel at the rate of 15ml/s as a result of the density difference of the acid from the reacting component. To avoid wastage of acid, it is recycled to an acid tank which has 1000 L capacity. The acid drained from the reaction vessel, picks up 50 g/L solids from the reactor. Acid is fed once again to the process from acid tank. When the process is started, the acid is almost pure in the tank as a result of filtration. As the reaction proceeds, acid in the tank gets more and more contaminated with the solids. The concentration of the solids should not exceed 100 g/L from the process point of view. The batch time is 16h. Estimate whether the concentration of the solids will exceed 100g/L during the batch reaction.
