8. Radiolysis of water produces hydrated electrons along with hydroxyl radicals and small amounts of hydrogen atoms. The alcohol serves as a scavenger for the OH radicals and permits observation of the reaction of the hydrated electrons with other solutes. The use of high pH is for preventing the reaction of hydrated electrons with protons that are also formed in the radiolysis.
