Question

Write two differences between dried and soft extract​

Answer 1

Answer:

Soft extracts are preparations of an intermediate consistency—between liquid and dry extracts. They are obtained by partial evaporation of the solvent used for preparation. Only ethanol of suitable concentration or water is used. Soft extracts generally have a dry residue greater than 70% w/w.

Answer 2

Answer:

To isolate a specific chemical, organic chemists frequently utilize extraction. A solute is moved from one phase to another during the extraction process in order to be separated from contaminants or unreacted starting substances.

Explanation:

Soft extract:

1. Preparations with consistency between liquid and dry extracts are called soft extracts.
2. They are produced by partially evaporating the preparation solvent.
3. Water or ethanol at an appropriate concentration is the only option.
4. Dry residue from soft extracts is often more than 70% weight to weight.

Dried extract:

1. Dry extracts are solid preparations that are produced after the solvent used to create them evaporates.
2. Dry residue in dry extracts is often more than 95% weight to weight.
3. Using acceptable inert materials or a dry extract of the vegetable or animal matter used for the production, standardized dry extracts are adjusted to the required quantity of components.
4. When appropriate, the monograph for a dry extract specifies a limit test for the extraction solvent.

Hence, the differences between dried and soft extract are mentioned above.
