Mariam Bentley · Answer 1

PH scale is from 1 to 14 and indicates how acidic or basic a solution is. To find pH or pOH we need to know the H⁺ ion concentration or OH⁻ concentration.

pH can be calculated using the following equation;

pH = - log[H⁺]

the H⁺ concentration of the given acid is 1.0 x 10⁻⁴ M. substituting this we can find the pH

pH = - log[1x10⁻⁴]

pH = 4

answer is 1) 4
