Phenolphthalein would turn pink when added to Drano, which is a strong alkaline substance. This color change indicates that the solution has become basic.
No, there should be no gas formed when mixing Drano and vinegar. The main ingredient in Drano is NaOH, and vinegar is acetic acid. So, the chemical reaction would be...NaOH + CH3COOH ==> CH3COONa + H2O. Neither is a gas.
The color change that occurs when iodine solution is added to starch is a dark blue or purple color. This reaction is commonly used to test for the presence of starch in a solution.
Chlorhexidine itself is a white or colorless compound. Any colored chlorhexidine solution would likely have added dyes or pigments to give it a specific color.
The addition of green color to a phospholipid molecule would not cause any change in the molecule's physical or chemical properties. Phospholipids are structural components of cell membranes with a hydrophilic head and hydrophobic tail, and the addition of a green color would not affect their structure or function.
the food coloring slowly moves around in the glass (like smoke would) and that is happening because the particles in the food coloring are not use to the temperature of the water,but as the particles get use to the temperature they move a little faster and spread everywhere in the water. Slowly disperse throughout the water, this is because of diffusion.
you would expect a color change in oil of wintergreen because it has an OH group added to the FeCl3 which causes a purple color
It is the paint, the color is just color and does not change the base paint. Depending on the grade of paint it may not cover as well as it would with color added.
it will be deep red colour if added to acidic solutions.
A deep blue colour
If by "use" you mean, "DRINK".. I would imagine fairly quickly yes. If you USE drano, I highly doubt it will do you ANY harm at all.Also, if you have the jug in your hand and are considering it.. I stress you to talk to someone.If you are about to use drano on a drain, good luck. Hope everything flows well for you.

When ammonia is added to mustard, a color change would typically result in a yellow or orange-yellow color becoming more intense or bright. This is due to the alkaline nature of ammonia enhancing the yellow pigment present in mustard.
The color observed would be red. Magenta is a combination of red and blue light, while yellow is a combination of red and green light. When magenta and yellow light are added together, the red components mix to create the observed red color.
The color change that occurs when iodine solution is added to starch is a dark blue or purple color. This reaction is commonly used to test for the presence of starch in a solution.
If Ag+ is added to a dilute solution containing FeCl4-, a white precipitate of AgCl would form. This is because Ag+ ions react with Cl- ions to form AgCl, causing the color of the solution to change from the original color of the FeCl4- solution to white due to the formation of the precipitate.
I would take the "P" trap apart and clean it or replace it. There are some things Drano will not remove.
No particular set of colors are used to make black. Black is actually better described as a "shade" or "intensity". Completely black would be an absence of all reflected color. Any color added to it would make it lighter and less black.
