    Ethanol precipitation - Wikipedia

    This means that adding ethanol to solution disrupts the screening of charges by water. If enough ethanol is added, the electrical attraction between phosphate groups and any positive ions present in solution becomes strong enough to form stable ionic bonds and DNA precipitation. This usually happens when ethanol composes over 64% of the solution.
