WebCalculate the pH of a buffered solution prepared by dissolving 21.5 g benzoic acid (HC7H5O2) and 37.7 g sodium benzoate in 200.0 mL of solution. arrow_forward A good buffer generally contains relatively equal concentrations of weak acid and conjugate base. WebThe pH is equal to 9.25 plus .12 which is equal to 9.37. So let's compare that to the pH we got in the previous problem. For the buffer solution just starting out it was 9.33. So we … man with jeans

WebDec 30, 2024 · Use the 1:1 ratio formula because one mole of HCl reacts with one mole of NaOH – HCl + NaOH → NaCl + H2O. Multiply the molarity of the strong base NaOH by the volume of the NaOH ( MB × VB = 0.500 M × 20.70 mL ). Divide this answer (10.35 M × mL) by the volume of the acid HCl (0.15 mL) MA = (MB × VB)/VA = (0.500 M × 20.70 mL)/0.15 mL … 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.
