If the solution is neutral, then it would turn green. B. blue turns yellow in the presence of acidic solutions and blue in the presence of basic solutions.
Bromthymol Blue, when heated in a solution, indicates carbon dioxide. If there is carbon dioxide in the solution, it will turn bright yellow (when heated).
your unknown solution made methyl red turn yellow. it also made phenolphthalein stay clear. what rang of pH does your unknown solution have?
Aspirin is acidic, so it would turn red.
lemon juice
it will turn a yellow colour
Phenol red indicates for acidic pH. When the red solution turns yellow it means the solution has a low pH. For Example: CO2 dissolves into water and forms carbonic acid which lowers the pH and the solution would turn yellow.
The solution will turn yellow
carbon dioxide from the plant and the more yellow the solution is the more Carbon Dioxide there is. The greener or bluer it is, the less carbon dioxide.
It would turn red in strong acid, orange/yellow in a weak acid, green in a neutral solution, blue in a weak base and purple in a strong base
If the solution is neutral, then it would turn green. B. blue turns yellow in the presence of acidic solutions and blue in the presence of basic solutions.
Yellow.
Bromthymol Blue, when heated in a solution, indicates carbon dioxide. If there is carbon dioxide in the solution, it will turn bright yellow (when heated).
A phenol red solution is yellow initially. When the solution is exposed to something basic the color will shift from yellow to red to fuschia. Adding enough acid will turn the solution yellow again.
A simple test for testing sugar in a solution is by Benedict solution. Add Benedict solution to the solution on heat it will turn brick red or yellow depending upon its concentration.
I think it has to do with the hardness of the water, (presence of calcium, magnesium, etc. that get oxidized by the chlorine and make the water yellow). Looking for a solution myself as I have well water.
If China rose solution is an acid, then it would turn red. If it's a base, it would stay blue.
