the ph indicator bromothymol blue turns yellow when co2 gas is added to a solution and blue when co2 is removed from a solution.
which statement is a hypothesis you could test using a solution with bromothymol blue? a. if yeast cells give off o2, then the solution will turn from yellow to blue. b. if fish give off heat, then the solution will turn from blue to yellow. c. if water plants take in co2, then the solution will turn from yellow to blue. d. if algae give off o2, then the solution will turn from blue to yellow.
C. if water plants take in co2, then the solution will turn from yellow to blue.
Explanation;
-Bromothymol blue is a pH indicator that is mostly used in applications that require measuring substances that would have a relatively neutral pH. A common use is for measuring the presence of carbonic acid in a liquid or dissolved carbon dioxide.
-The indicator changes color over a pH range from 6.0 (yellow) to 7.6 (blue). It is a good indicator of dissolved carbon dioxide (CO2) and other weakly acidic solutions.
-Low levels of carbon dioxide or acid in solution with bromothymol blue indicator will appear blue. As the level of carbon dioxide or acid increases, the solution will gradually take on a yellow tint.
The Answer is here Nuclear energy has no place in a safe, clean, sustainable future. Nuclear energy is both expensive and dangerous, and just because nuclear pollution is invisible doesn't mean it's clean
It is described as having a marshy surface where mosses, lichens, berries and low shrubs grow with mucky soil and permafrost underneath. This is a term use to describe an ecological community in which moisture and temperature are high. This is a northern hemisphere habitat with wet soil.
When white light passes through the prism ,different colours suffers deviation through different angles and light appears to be dispersed. But in a hollow prism dispersion does not take place as all the colours travel with same speed in the air inside hollow prism. Thus no angular dispersion is there.
