WebAs you saw in the video, the pH of a 0.1 M solution of acetic acid, HC2H3O2, (Ka ≡ 1.8 × 10−5) is 2.9. Based on this observation, which statement below best describes the pH of a … Web30K views 2 years ago To calculate the pH of a strong acid like HCl (hydrochloric), recognize that [H+] = 1.0 M simply because it IS a strong acid. Now you can use pH = -log [H+] Show more... bing search marizy eat oats
How to tell the pH of HC2H3O2? - Chemistry Stack …
WebMar 26, 2024 · Since HCl is a strong acid, it completely ionizes, and the pH of HCl in solution can be found from the concentration (molarity) of the H+ ions, by definition equal to 0.100 … WebThe answer to the question is here, Number of answers:2: A 1.0L buffer solution contains 0.100 mol of HC2H3O2 and 0.100 mol of NaC2H3O2. The value of Ka for HC2H3O2 is 1.8Ă—10â’5. Part A Part complete Calculate the pH of the solution upon the addition of 0.015 mol of NaOH to the original buffer. Express the pH to two decimal places. pH p H = … WebSo, now that we're adding the conjugate base to make sure we have roughly equal amounts, our pH is no longer 2. It might be somewhere like a 5. So now we have a strong buffer with a lot of capacity, but our pH of this buffer solution is very different from the pH of just the weak acid/conjugate base we started with.
