pH is a scale that was introduced by sorenson,The terms pH
& pOH literally means potenz(strength) of Hydrogen ions &
hydroxyl ions.Thus it can be measured for any compound that
can be ionised to give these ions in their aqueous
solutions & not for other compounds.Furthermore the H+ ions
& OH- ions can dissociate to a extent of 10^-7 & not more
than that for any aqueous solution i.e.10^-7+10^-7=10^-14
