Abstract
IT has recently been experimentally demonstrated that in water close to pH. 7 (ref. 1) and at pH. 4 (ref. 2), the reducing radical formed during radiolysis bears a unit negative charge. This suggests that an ejected electron escapes from its parent H2O+ ion. It follows that H2O+ ions should temporarily exist in a spur. The H2O+ ions, or their hydrolysis products, H3O+(H2O+ + H2O→H3O+ +· OH), might cause a suitable solute to ‘see’ a spur as a volume which temporarily has a lower pH than the body of the solution. The purpose of this communication is to present some experimental results which we interpret as evidence for this effect.
