How do you dilute 99% isopropyl alcohol to 70 ounces?
(Reading the first example, from left to right) Let’s say the scientist has an 8 oz (V1) bottle of 99% (C1) IPA and they want to dilute it to 70% (C2).
By using the above equation, we find that they would need to add 3.31 ounces of (distilled) water with 8 ounces of 99% IPA, inside an 11.31 ounce (V2) bottle or larger..

Should I dilute 99 isopropyl alcohol?
A good rule of thumb for diluting 99% IPA to 70% (v/v) is to expect a decrease in volume of 2.5–3.0% so instead of 70% IPA and 30% DI water you typically end closer to 70% IPA and 32.5% DI water.
