The pH indicator bromothymol blue is blue in an alkaline solution and yellow in an acidic solution. A slight increase in acidity, such as when CO2 gas is added, causes a solution with the indicator to change from blue to yellow.A solution with the indicator would turn from blue to yellow when which combination of factors exists? Select the two correct answers.A.Algae in the solution are placed under a bright light.B.A water plant in the solution is placed on a sunny windowsill.C.A person blows air into the solution through a straw.D.Yeast cells and sugar are placed in the solution.

Bromothymol blue is an indicator that turns yellow in solutions when the pH is below 6, green when the pH is between 6 and 8, and blue when the pH is above 8. What color would it turn when added to water?Question 4Select one:a.pinkb.yellowc.greend.blue

Bromothymol Blue is one of the indicators we will be using in next week's experiment.  What pH range does Bromothymol Blue change colour?

On opening the soda water bottle the dissolved CO2 comes out. Wouldthe pH of the solution increase or decrease as the gas comes out?Explain your answer either way.A solution ‘X’ gives orange colour when a drop of universal indicatoris added to it. On the other hand, another solution ‘Y’ gives bluish-green colour when a drop of universal indicator is added to it.Whatare the types of solution ‘X’ and ‘Y’ and what type of pH would theyhave?

Molecules on an acid-base indicator react chemically with ions in a solution, causing the indicator to change color. Which ions in the solution cause this reaction? (3 points)Oxygen ionsWater ionsHydrogen ionsNitrogen ions

Which method uses the color changes of several indicators to measure the pH of a solution?
