Ph of solution with 8.5 an 3.4
WebJul 9, 2014 · You will use the following equation to find the pH. pH = -log [H+] This means you take the negative log of the hydrogen ion concentration to find the pH. The hydrogen ion concentration is the same as the concentration of the acid because HCl is a strong acid and dissociates as follows: HCl -> H + + Cl− (notice the 1:1 ratio of HCl and H +) WebCalculate the pH of each solution given the following: Part A [H3O+]=3×10−8M Express your answer using one decimal place. Part B [H3O+]=6×10−6M Express your answer using one decimal place. Part C [OH−]=8×10−2M Express your answer using one decimal place. Part D [OH−]=5.5×10−3M Express your answer using two decimal places. Part E …

WebpH is a logarithmic function of [H + ]: pH = −log [H+] pH is usually (but not always) between 0 and 14. Knowing the dependence of pH on [H + ], we can summarize as follows: If pH < 7, … 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.
WebIf the base has an OH - concentration of 0.001M, find the pH. Solution: First find the pOH, (similar to finding the pH,) then subtract the pOH from 14. OH - = 0.001M = 10 -3; pOH = -log [OH -] = -log (10 -3) = +3 = pOH pH = 14 - pOH; pH = 14 - 3 = 11 = pH pH Principle: pH and pOH must always equal pKw (14). Click for larger image pH Scale: 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 …
