Question

Distilled water has a hydronium ion concentration of 1

What is the pH of distilled water?


7

–7

10

1 × 10 –7

Answer 1

The value of hydronium ion ought to be 1* 10-^7
In that case, the value of pH can be calculated using the formula:
pH = - Log [H3O+].
pH = - Log [1 * 10^-7]
pH = - [-7]
pH = 7
From this calculation, the correct answer will be A, which is 7.
