Final answer:
When IRM is supplied as a powder and liquid, it is mixed by adding the powder to a flask, dissolving it with distilled water, and then thoroughly mixing the solution.
Step-by-step explanation:
When IRM (Isolation and Recovery Medium) is supplied as a powder and liquid, it is mixed by following a specific procedure:
- The powder is added to a flask.
- Distilled water is carefully added to the flask.
- The solution is swirled until all of the powder dissolves.
- More distilled water is added up to the line etched on the neck of the flask.
- The flask is capped and inverted several times to completely mix the solution.
This process ensures that the powder is fully dissolved and well-mixed with the liquid component of IRM.
