Question

What is the pH of an aqueous solution at 25.0°C in which [H+] is 0.0025 M?
A) 5.99 B) 2.60 C) -2.60 D) -5.99 E) none of the above

Answer 1

Answer:

B

Explanation:

by using formula

pH = –log(0.0025) = –log(25/10⁴)

= 4 – log(25) = 2.60

Answer 2

The answer is option B) 2.60

How to find pH?

To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = - log [H3O+].

by using formula

pH = –log(0.0025) = –log(25/10⁴)

= 4 – log(25) = 2.60

What Is Meant By The pH Calculation Formula?

The measure of hydrogen ion concentration used to determine the acidity or alkalinity of a solution is known as pH.
