  • 2. 

    Vinegar means ...... % of Acetic acid

    • 4 - 6 % Acetic acid

    • 6 - 10 % Sulfuric acid

    • 6 - 10 % Acetic acid

    • 10 - 15 % Acetic acid

    Correct Answer
    A. 6 - 10 % Acetic acid
    Explanation
    Vinegar is a liquid that is primarily composed of acetic acid. The given answer states that vinegar contains 6 - 10% acetic acid, which means that this percentage range represents the concentration of acetic acid in vinegar. This implies that for every 100 parts of vinegar, there are 6-10 parts of acetic acid.

    Below Flowsheet is used for manufacturing of  - ProProfs

    Below Flowsheet is used for manufacturing of 

    • Acetylene

    • Acetaldehyde

    • Acetic acid

    • None of them

    Correct Answer
    A. Acetaldehyde
    Explanation
    The given flowsheet is used for the manufacturing of Acetaldehyde. This can be inferred from the fact that the flowsheet does not include the manufacturing processes for Acetylene or Acetic acid, leaving Acetaldehyde as the only remaining option.

    Rate this question:

  • 4. 

    Reaction is carried out at ..... oC in manufacturing of acetic acid

    • 50 oC

    • 56 oC

    • 55oC

    • 65oC

    Correct Answer
    A. 55oC
    Explanation
    In the manufacturing of acetic acid, the reaction is carried out at 55oC. This temperature is likely the optimal temperature for the reaction to occur efficiently and produce the desired amount of acetic acid. Higher temperatures may lead to unwanted side reactions or degradation of the product, while lower temperatures may slow down the reaction or make it impractical. Therefore, 55oC is the suitable temperature for the manufacturing process.

    Application of Butanol 

    • As a fuel

    • As a solvent

    • Plasticizers

    • All of above

    Correct Answer
    A. All of above
    Explanation
    Butanol can be used as a fuel because it has a high energy content and can be easily blended with gasoline. It is also used as a solvent in various industries due to its ability to dissolve a wide range of substances. Additionally, butanol can be used as a plasticizer, which is a substance added to plastics to increase their flexibility and durability. Therefore, all of the given options are correct applications of butanol.

    ________ is the By-product produced during the fermentation process

    Correct Answer
    CO2
    Explanation
    CO2 is produced as a by-product during the fermentation process. Fermentation is a metabolic process in which microorganisms, such as yeast or bacteria, convert sugars into alcohol, acids, or gases. CO2, or carbon dioxide, is one of the gases produced during this process. It is a waste product of the metabolic activity of the microorganisms and is released into the surrounding environment. CO2 is commonly observed in the form of bubbles in carbonated beverages, as it is trapped in the liquid during the fermentation process.

    ________,________Catalyst is used for manufacturing of Ethanol 

    Correct Answer
    Invertase
    Zymase
    Explanation
    Invertase and Zymase are enzymes that are used in the manufacturing process of ethanol. Invertase is responsible for converting sucrose into glucose and fructose, while Zymase is responsible for fermenting glucose and fructose into ethanol. Therefore, both enzymes play a crucial role in the production of ethanol.
