The buffer in lemonade
網頁Comparing the number of moles of sodium hydroxide used in lemonade and citric acid titration to reach equivalence point, what does this tell you about the property of the buffer in lemonade in controlling the ? 10. In both titration curves, what happens to the pH after can you answer 5-9-10-11, please 🙏 🥺 Show transcribed image text Expert Answer 網頁A buffer solution is a solution of a conjugate acid/base pair that resists changes in pH. Since buffers are just solutions of conjugate acid/base pairs, we can use weak acid K,'s to calculate the pH of buffer solutions. A buffer equation has been developed to simplify buffer calculations.
