if i drop a phenol red tablet into a jar that has only water and spinach leaves what color will the water be after 30 minutes in the sun?
Homework Answers
The color will change from yellow back to reddish color. This change in color is because of photosynthesis performed by spinach leaves by taking CO2 from phenol red. Because of which pH of the solution will increase leading to change in color.

You have been given a jar of red fruit punch and been asked to determine the concentration of red dye in the fruit punch. You obtain a stock solution of this red dye and it has a concentration of 0.00485 M (in the lab room, the stock solution is found in the hood). You take 10.0 mL of this stock solution and dilute it to 100.0 mL. You call this your standard solution. Usinga colorimeter, you determine that the red...

A phenol red glucose broth with a Durham tube has been inoculated and incubated. After 48 hours, the broth is turbid and bright yellow and approximately half of the contents of the Durham tube contains bubbles. Interpret these results. The organism will ferment lactose as well. The organism is fermenting glucose. The organism is an obligate anaerobe. The organism is fermenting lactose and producing ethanol and CO2. What can be detected using SIM medium? Check all...
