Titration curves. It makes sense to look at titration curves before you look at indicators. Start by reading the page about pH (titration) curves. This is quite a Measuring the pH at regular intervals during the titration of a weak acid with a strong base can be used as a method for calculating the pKa of the acid, using the
Redox titration (also called oxidation-reduction titration) is a type of titration based on a redox reaction between the analyte and titrant. Redox titration may involve the use of a redox indicator and/or a potentiometer. Example. An example of a redox titration is treating a solution of iodine with a reducing agent and using starch
This course covers modern and advanced methods of elucidation of the structures of organic molecules, including NMR, MS, and IR (among others). The fundamental physical and chemical principles of each method will be discussed. The major emphasis of this course is on structure determination by way of interpreting the
This page describes how simple acid-base indicators work, and how to choose the right one for a particular titration. Warning: This page assumes that you know about pH curves for all the commonly quoted acid-base combinations, and weak acids (including pKa). Phenolphthalein is
A redox titration to determine the vitamin C concentration of foods and supplements 17. 9A. Boiling point elevation . .. www.chemguide.co.uk or text books) to learn about redox titrations. Use LabSkills or construct a balanced redox equation for the reaction between potassium dichromate(VI) and ammonium iron(II)
A solution of hydrogen peroxide is mixed with one containing potassium iodide, starch and sodium thiosulfate. After a few seconds the colourless mixture suddenly turns dark blue. This is one of a number of reactions loosely called the iodine clock. It can be used as an introduction to experiments on rates / kinetics.
pH (TITRATION) CURVES. This page describes how pH changes during various acid-base titrations. The equivalence point of a titration. Sorting out some confusing terms. When you carry out a simple acid-base titration, you use an indicator to tell you when you have the acid and alkali mixed in exactly the right proportions
Redox titrations. Reduction and oxidation reactions. Redox titrations depend on the transfer of electrons between the two reacting species in solution. They may or may not be self-indicating. Examples include: 1 Determination of copper(II) by displacement of iodine followed by titration with sodium thiosulfate. 2 Reaction of
