How to Tell Which Indicator to Use Titration Curve
B You may be able to approximate the pH of the salt solution using the relative strength of acid and base as shown above. Indicators are used to find pH value in equivalence point. Measurenet Thermometric Titration Setup Chemistry Labs Setup Office Phone Explain how to use a pH titration curve to determine the acid dissociation constant of an unknown acid. . For the titration of weak acid - strong base phenolphthalein but not methyl orange is a suitable indicator. A pH curve is a graph produced from a titration that shows how the pH of a solution changes when we add an acid or alkali to it. 1 The equivalence point of an acid-base reaction the point at which the amounts of acid and of base are just sufficient to cause complete neutralization. For example methyl red is an indicator that goes from red to yellow over a pH range of about 44 to 62. Going back to the example the pH of the titration of a strong acid by a strong ba...
