Double Indicator Titration

When we have a mixture containing Na₂CO₃ and NaOH and you titrate it with a standard solution of HCl, you will need to use two indicators; one after another. The video below will explain how double indicators work in titration, using the above mentioned as the example.



An interesting question to take note. In what circumstances would the use of double indicator titration be limited?

Note: This video will assume that you do have an awareness the meaning of the following terms such as "working pH" and "equivalence point". They are not explicitly stated in the video.
