Answer:
Step-by-step explanation:
To produce a 50% salicylic acid solution using salicylic acid 100 (powder form), follow these steps:
1. Take 50 grams of salicylic acid 100 powder and weigh it. This is equal to half of the final solution volume of 100ml.
2. In a tiny amount of distilled water, dissolve the salicylic acid powder. Stir the mixture until the powder has fully dissolved.
3. Once the powder has been dissolved, gradually add the remaining distilled water (50ml) to the solution. Combine thoroughly.
4. Fill a clean container halfway with the solution and mark it with the concentration, date, and your name.
5. Keep the solution cold and dry, away from light.
Note: It is very important to use distilled water to produce the solution since tap water might include pollutants that can harm the solution. When working with salicylic acid, it is also vital to use gloves and safety goggles since they can irritate the skin and eyes.
