For a solution with an [oh−] of 10−8 m, what would be the value of [h+] , ph and poh, respectively? 1. 106 m, 6, 8 2. 10−6 m, 6, 8 3. 10−6 m, 8, 6 4. 10−14 m, 6, 8 5. 10−6 m, 6, 14 6. 10−14 m, 8, 6
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
