... This is a typical case of « small cause - big effect » because from two neighbouring water molecules, through a tiny displacement, is formed an ion pair – a hydronium ion H3O+ and a hydroxide ion OH- - which in turn hydrolyse 10, and their electric field induces new structures. This phenomenon of pr ...
