Which statement best describes the ph of pure water? it is neutral because the concentration of hydronium ions equals that of hydroxide ions. it is neutral because the pure liquid contains neither hydronium ions nor hydroxide ions. it is acidic because it has a hydronium ion concentration of mc027-1.jpg. it is basic because it has a hydroxide ion concentration of mc027-2.jpg.

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.

the answer is a
