To set up a titration, you need an Erlenmeyer flask or beaker, an excess amount of solution of known concentration (titrant), a precisely measured amount of analyte (used to make the solution of unknown concentration), an indicator, a calibrated buret (a glass device that allows the precise ...
Chemists typically record the results of an acid titration on a chart with pH on the vertical axis and the volume of the base they are adding on the horizontal axis. This produces a curve that rises gently until, at a certain point, it begins to rise steeply. This point – called the ...
How is titration used in water testing? Titration is another way to test for pH. Basically, the tester starts with a solution he or she already knows the concentration of. The tester thenuses that knowledge to determine the concentration of an unknown solution. ...

To calculate the pH of a buffer solution when base is added, the Henderson-Hasselbalch equation, pH = pKa + log (acid/base), is used. The mol of base is added to the buffer's base, and the base's mol is subtracted from the buffer's acid. These new mols are used to find the ...
If a titration of 0.5533 grams of KHP needs 25.84 mL of a NaOH solution to reach the equivalence point, what is the concentration of the NaOH? How to find molar mass from titration? What is the molarity of NaOH if it takes 40.0 mL of NaOH to...

How would you prepare 150 \ ml of 0.2 \ M acetate buffer pH 4.5 from 1 \ M acetic acid and 2 \ M sodium acetate? (pKa of acetic acid is 4.75)? How do you find pKa from a titration curve? Calculate the pH of 0.105 mol dm^3 CCl3COOH (trichloroacetic acid), pKa = 0.52. a)...
Derive the scale of pH from the property ionization of water. Indicate the neutral point, the acidic and base areas. If a solution is at pH 4, how many hydrogen ions are present in a final solution ending up at pH 7? When the pH of a solution changes from a value of 5 to a valu...
