Question

which of the following is/are correct for pH?
1. A scale for measuring hydronium ion concentration.
2. Values less than 7 on the pH scale represent an acidic solution.
3. As the pH value increases from 7 to 14, it represents an increase in hydrogen ion concentration in the solution.​

Answer 1

Answer:

1, 2 are correct

Explanation:

3 is incorrect as when ph increases hydrogen ion concentration decreases

And 1 and 2 are correct as pH is a scale for maeusuring Hydronium ion concentration and values less than 7 on the pH scale are considered to be acidic.
