The following indicators are available:

Question

Indicator pH Range
Ind1 3,1 – 4,4
Ind2 6,0 – 7,6
Ind3 8,3 – 10,0
1. Which indicator will be the most appropriate to use and why?
2. Give the name of that indicator

Answer 1

1. The most appropriate indicator to use would depend on the pH range that needs to be measured.

- If the pH range is between 3.1 and 4.4, Indicator 1 (Ind1) would be the most appropriate.
- If the pH range is between 6.0 and 7.6, Indicator 2 (Ind2) would be the most appropriate.
- If the pH range is between 8.3 and 10.0, Indicator 3 (Ind3) would be the most appropriate.

Without knowing the specific pH range to be measured, it is not possible to determine which indicator is the most appropriate.

2. The specific name of the indicator cannot be determined without more information. The indicators are referred to as Ind1, Ind2, and Ind3 in the given information.
