Answer from: Quest
answer: option (a) is the correct answer.
explanation:
the measurement of hydrogen ions in a solution is known as ph.
if ph of a solution is less than 7 then the solution is acidic. if ph of a solution is greater than 7 then the solution is basic.
when the ph of a solution equals 7, then the solution is considered as neutral.
the ph of pure water is 7, therefore, it means that concentration of hydronium ions equals that of hydroxide ions.
