WebAug 29, 2024 · Solution: The concentration can be calculated by dividing the amount of solute by the volume of solution [Eq. 3.11.1 ]: c KI = n KI, mol V solution, L. We obtain n KI from the mass of KI added to the flask: m KI = 43.2874 − 30.1544 g = 13.1330 g. n KI = 13.1330 g × 1 mol 166 .00 g = 7.9115 × 10 − 2 mol. WebThe unit for the concentration of hydrogen ions is moles per liter. To determine pH, you can use this pH to H⁺ formula: pH = -log ( [H⁺]) Step by Step Solution to find pH of 0.0036 M : Given that, H+ = 0.0036 M Substitute the value into the formula pH = -log ( [0.0036]) pH = 2.443697 ∴ pH = 2.443697 Its Acidic in Nature Similar pH Calculation
