Abstract
In above short notes, first we have poiuted out that there is a numerical relation between theionic diametre and the number of watcr-molecules attached to thc ion. Sccondly, we have cxplaincd themauner of attachment of water-molecnles t, the ion based upon the atom model of Lewis and Langmuir.Thirdly, we have suggested the mechanism of ionisation from a relation which is derived from a certaincomputntion using the data of the volume-change of the solution
