How to Determine Which Indicator to Use for Titration
EBT is the indicator used in the determination of hardness. An acidbase indicator eg phenolphthalein changes color depending on the pH. 18 3 Identify An Appropriate Indicator For A Titration Hl Ib Chemistry Youtube Now you might think that when you add an acid the hydrogen ion would be picked up by the negatively charged oxygen. . Colour in acidic solution. Universal indicator which is actually a mixture of several indicators displays a variety of colours over a wide pH range so it can be used to determine an approximate pH of a solution but is not used for titrations. 1 pH range of the indicator cuts the. Molarity is the concentration of a solution expressed as the number of moles of solute per litre of solution. Thus the indicators like methyl orange methyl red and phenolphthalein can show the colour change in the ph range of 4t0 10. What factors govern the choice of a suitable indicator for an acid base titration. ...
