WebJan 31, 2016 · The pH of pure water will thus be pH = −log([H3O+]) pH = −log(10−7) = 7 Now, let's assume that you're working with a 1.0-L solution of pure water and you add some 10−8M hydrochloric acid solution. To keep calculations simple, let's assume that the volume remains unchanged upon adding this hydrochloric acid solution. WebNov 24, 2024 · Plug in your value to find pH = −log(3.5 ⋅ 10−3) pH = −log(3.5) − log(10−3) pH = 3log(10) − log(3.5) pH = 2.46 −−−−−−−−− The answer is rounded to two decimal places … WebApr 8, 2024 · Calculate the pH of a Benzoic acid solution of concentration 0.01 M. Solution: For a 0.01 M concentration of Benzoic acid sample, K a (Acid dissociation constant) is 6.5 x 10-5. Now, a Benzoic acid sample 0.01 M concentration is when mixed with water or aqueous solution, the dissociation reaction can be expressed as – how do i get a new pps card
