A solution is classified as basic by using two indicators to determine that solution had a pH between 9.6 to 10.1. What are the indicators used? What would be observations been?
The two commonly used indicators to determine if a solution is basic are phenolphthalein and bromothymol blue.
1) Phenolphthalein: This indicator is colorless in acidic solutions and turns pink or magenta in basic solutions. If phenolphthalein is used, the observation would be a color change from colorless to pink or magenta, indicating that the solution is basic.
2) Bromothymol Blue: This indicator is yellow in acidic solutions and turns blue or green in basic solutions. If bromothymol blue is used, the observation would be a color change from yellow to blue or green, indicating that the solution is basic.
By using these indicators and observing the color change, it can be determined if the solution falls within the basic range with a pH between 9.6 to 10.1.
