Diluting powder in water involves carefully mixing the substances to achieve a uniform solution or suspension. Based on the provided reference, here is a specific method to dilute concentrated powder in water to a 400 ml volume.
Step-by-Step Dilution Process
Following the steps outlined in the reference ensures proper mixing and preparation of the powder solution:
- Pour the Powder: Begin by pouring the concentrated powder directly into a bottle.
- Add Water: Carefully add room temperature water to the bottle until the total volume reaches 400 ml.
- Secure the Bottle: Close the bottle tightly to prevent spills during mixing.
- Shake Vigorously: Shake the bottle vigorously, using a bottom-up motion, to help the powder disperse in the water.
- Disperse Deposit: Slightly tap the bottom of the bottle. This action helps to dislodge and disperse any powder that may have settled at the bottom.
- Allow to Stand: After shaking and tapping, let the bottle stand. It is ideally recommended to let it stand overnight.
Why Let It Stand?
Allowing the mixture to stand after shaking is crucial for a specific reason mentioned in the reference: to give time for foam to disappear. Vigorously shaking the powder and water can create a significant amount of foam. Letting the solution rest allows this foam to dissipate, resulting in a clearer liquid preparation.
Key Considerations
- Always use room temperature water as specified.
- Ensure the bottle is securely closed before shaking.
- Tapping the bottom is a practical step to ensure all powder is incorporated.
- Patience is key; allowing sufficient standing time (like overnight) ensures the foam subsides completely.
This specific method, derived directly from the provided reference, details how to prepare a 400 ml dilution of concentrated powder in water.
