Answer:
pH is measured with the pH scale which is also known as universal indicator which is the colour combination of different acid base indicators it will indicate the pH level by different colour coding.
pH level varies in water for hydronium and hydroxyl ions.
pH level is directly proportional to oo hydroxyl ions where as inversely proportional to the hydronium ions.
when the concentration of hydroxyl ion increases PH value also increases but when the concentration of hydronium ion increases PH value decreases.
we can say that in this way PH value is related to hydronium and hydroxyl ions in water.
