How does the efficiency of extraction vary?

• The efficiency of extraction varies based on extraction method, material properties, and process conditions.

• The efficiency of extraction is constant regardless of method.

• Extraction efficiency is solely determined by the temperature.

• Material properties do not influence extraction efficiency.

What factors influence the choice of extraction method?

• The time of day the extraction is performed

• The color of the extraction equipment

• The personal preferences of the technician

• Factors influencing the choice of extraction method include material nature, desired purity, scale, cost, environmental impact, and target compound properties.

Explain the role of solvents in the extraction process.

• Solvents dissolve target compounds, enabling their separation and extraction based on solubility.

• Solvents are used to increase the temperature of the extraction process.

• Solvents act as catalysts to speed up chemical reactions during extraction.

• Solvents are primarily used to filter out impurities from the target compounds.

What is the significance of temperature in extraction?

• Temperature has no effect on extraction processes.

• Temperature significantly influences the solubility and efficiency of extraction processes.

• Higher temperatures always lead to better extraction results.

• Temperature is only relevant in solid-state extractions.

How can extraction be optimized for better yield?

• Optimize temperature, time, solvent choice, and particle size.

• Use only water as a solvent

• Increase extraction pressure only

• Shorten extraction time drastically

Discuss the environmental impacts of extraction methods.

• Extraction methods improve biodiversity and habitat quality.

• Extraction methods have no impact on the environment.

• Extraction methods have significant environmental impacts, including habitat destruction, soil erosion, water pollution, and loss of biodiversity.

• Extraction methods only affect air quality without impacting water or soil.
