WebMar 8, 2024 · Decrease or increase depends on your frame of reference. If you compare it with a 1:1 buffer where the pH = pKa, it decreased because there is a higher concentration of acid than conjugate base. If you compare it to the pH of 0.3 M formic acid (roughly pH = 2.1), then it increased because you added conjugate base (neutralized and diluted the acid). WebWhat is pH of 4.2 x 10-3 M NaOH ? in this case need to use K w expression---and assume all [OH-] in water soln is coming from exogenous base: [H+] = K w /[OH-] = 10-14 / 4.2 x 10-3 = 2.3 8 x 10-12 therefore pH = -log (2.3 8 x 10-12) = 11.62 .

Chemistry Acids and Bases pH 2 Answers Ernest Z. Jul 7, 2016 The pH is 7.08. Explanation: The base is so dilute that we must also consider the OH- that comes from the autoionization of water. H2O ⇌ H+ +OH- Kw = [H+][OH-] = 1.00 × 10-14 We start by noting that charges must balance.
WebNov 13, 2024 · The idea is to add titrant until the titrant has reacted with all of the analyte; at this point, the number of moles of titrant added tells us the concentration of base (or acid) in the solution being titrated. Example 10.2. 1: 36.00 ml of a … 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. Comment ( 4 votes) Upvote
