Question:
Why did the solution turn to pink at the end of titration (redox titration between sodium thiosulphate and sulphuric acid)? Explain your reasons.
Indicator:
- The indicator is an external substance that changes the colour of the solution when the titration is completed.
- Indicator gives different colour in acidic and basic medium.
- For acid base titration phenolphthalein indicator is used.
