Q1) pOH

the hydroxide ion concentration can be used to calculate the pOH of the solution

pOH can be calculated using the following equation

pOH = - log[OH⁻]

pOH = - log (10⁻⁸ M)

pOH = 8

therefore pOH of solution is 8

Q2) pH

by knowing the pOH value we can calculate the pH value

since

pH + pOH = 14

and pOH = 8

therefore pH = 14 - 8

pH = 6

Q3)

pH scale is used to determine how acidic or basic a solution is

knowing the pH value we can calculate hydrogen ion concentration

pH = - log[H⁺]

[H⁺] = antilog (-pH)

[H⁺] = antilog (-6)

[H⁺] = 10⁻⁶ M

answer is 2. 10 ⁻⁶ M, 6, 8
