What is the colour change range?Show answer
Because the colour switches over the range where neither form completely dominates, each indicator has a characteristic transition interval. Common examples:
What is choosing an indicator for a titration?Show answer
The key skill is matching the indicator to the equivalence point of the titration. You want the indicator to change colour exactly where the titration curve is steepest, so the colour change is sharp and corresponds to the equivalence point.
