So, for preparing 125 ml of 75% ethanol solution, one must take 98.684 ml of 95% ethanol solution and 26.316 ml of Water.How do you dilute 95% alcohol to 70%?
Preparation of 70% alcohol: 70% alcohol means 70 mL of alcohol should be present in 100 mL of solution. Therefore, if we take 74 mL of the 95% alcohol and make its volume up to 100 mL, the concentration of the obtained solution will be 70% by volume.How do you dilute 95 alcohol?
All we have to do is to subtract the volume of 95% alcohol from the volume of 75% alcohol, in this case: 1.26 x 1.00 = 0.26 l = 260 ml.
10.75 x 1000 = 750 ml.2This is the amount of pure alcohol.30.25 x 1000 = 250 ml.4This is the amount of water.- Add (10–8.42)= 1.58- ml of distilled water to 8.42- ml of 95% Ethanol and mix, you will get 80% Ethanol.
