Action of sodium hydroxide on 0.1 bromothymol blue?
The color is blue.
How is bromothymol blue made?
Bromothymol blue solution can be made by adding 20 milliliters of alcohol to 0.1 grams of bromothymol blue powder and 10 milliliters of 4 percent sodium hydroxide solution. Next, add one liter of of distilled water. If it looks green instead of blue, add some sodium hydroxide to it one drop at a time until it turns blue.
How do you prepare thymol blue indicator?
Bromothymol Blue (BTB)Bromothymol blue is an indicator, a substance that changes color as the pH of a solution changes. Bromothymol blue is yellow in acidic solutions and blue in basic solutions.BTB can be prepared by mixing 0.1 g (a pinch) of bromothymol blue powder in 10 mL of a 4% solution of sodium hydroxide.Add 20 mL of alcohol and dilute to 1 L with distilled water.The solution should be deep blue.If it is green, add sodium hydroxide solution drop by drop until the solution turns blue.Bromothymol blue can be purchased from scientific supply houses.CAUTION: Sodium hydroxide is corrosive; the BTB solution should be prepared in a laboratory. BTB stains hands and clothes. Have students wear goggles and follow safety precautions when using BTB solution.
