How to dilute 70% ethyl alcohol to 50%?
To make it 50% alcohol you need to have equal amount of water and alcohol in the solution. So, add 0.4 x ml of water. That gives you a solution of 0.7 x ml of each water and alcohol, i.e. 1.4 x ml of 50% alcohol. Therefore, you take 142.9 m l of 70% ethyl alcohol in the bottle and fill the rest of the bottle with pure water.
