Calculate the pH of a solution in which the concentration of the hydrogen ions is 1.0xx10^(-8) mol litre^(-1)

Answer»

Solution :Here ,although the solution is extremenly dilute ,the concentration given given is not an ACID or a base but that of `H^(+)` ions.Hence ,the PH can be calculated from the RELATION:
pH=`-log_(10)10^(-8)=-(-8log_(10)10)`
`=-(-8xx1)=8`
