a PH. but if the solution is KMnO4 here not hydrogen power
does it PH? explain plz....

Answer / yojana
pH range is 14 because water pKa value is 14.without water
we can't find pH .also as per equestion,
pH+ POH=14

Answer / omkar
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
