Question
I want to dilute Ethyl Alcohol 99.9% down to 70%. How should I do this, and what are the ratios? I want to make alcohol for personal use. Thank you in advance.
Answer
To dilute 99.9% ethyl alcohol to a concentration of approximately 70%, which is suitable for making hand sanitizer, you need to mix the alcohol with clean water.
You can calculate the ratio as follows:
If you want to make 100 ml of 70% alcohol:
- Use approximately 70.1 ml of 99.9% ethyl alcohol.
- Add approximately 29.9 ml of clean water.
Mix these two parts together to get approximately 100 ml of 70% alcohol solution. You can adjust this ratio based on the total volume you want to make. For example, if you want to make 1,000 ml, multiply all volumes by 10.
