Question

You are given four unknown solutions I, II, II, and IV. The pH values of these solutions
are found to be 3, 7, 8, and 10 respectively. Among the given solutions, which solution has
the highest hydrogen ion concentration?
(a) I (b) II (c) III (d) IV​

Answer 1

Answer:

(a) I

Explanation:

Because the ph value of 3 is an acid, So it has highest hydrogen ion concentration

Answer 2

Answer:

The highest hydrogen ion concentration is in the unknown solution I. Option (a) is correct.

Explanation:

• The pH value decides the hydrogen ion concentration in the given solution.
• If the pH value is lower, the hydrogen ion concentration is higher.

Of the given solutions, the pH value of the solution (I) is the lowest. So, it is the most acidic solution. Solution IV has the highest pH value. So, it is the least acidic solution. For a neutral solution, the pH value is $7$.

So, the highest hydrogen ion concentration is in the unknown solution I.

Option (a) is correct.
