Heating causes a bromthymol blue indicator solution to change yellow to blue rapidly why?
Bromthymol blue is an indicator solution that turns yellow in the presence of carbonic acid (H2Co3). Chemically, water and carbon dioxide combine to form carbonic acid. Heating the solution favors the dissociation of carbonic acid back to carbon dioxide and water and therefore the bromthymol blue returns to its less acidic state and back to it original blue color.

What is phenolphthalein?
it is a agar medium for Microbiology containing phenolphthalein biphosphate. It is used in Petri plates and detects the phosphatase character of microbial colonies but requires final addition of alkali to color the phenolphatlein and the color rapidly fades.
What is the dependent variable of Does stirring a solution make salt dissolve more rapidly?
The dependent variable is the rate of salt dissolution in the solution.
Why heating a can and putting it in water?
Heating a can and then submerging it in water can create a pressure difference between the inside and outside of the can. When the can is rapidly cooled in water, the pressure difference causes the can to collapse due to the external pressure being greater than the internal pressure.
Does heat cause molecules of sugar to leave sugar cube more rapidly when placed in a solution?
yes but dont eat it
Why do you use water-bath for evaporating salt soution?
A water bath is used for evaporating salt solutions to control the temperature of the solution, preventing it from boiling too rapidly and causing splashing or loss of material. The water bath provides a gentle and even heat transfer to the solution, aiding in the gradual evaporation of the solvent.

How do the heating of land and water different?
Land heats more rapidly and to higher temperatures than water. Land also cools more rapidly and to lower temperatures than water
How do the heating of land water differ?
Land heats more rapidly and to higher temperatures than water. Land also cools more rapidly and to lower temperatures than water

What is the scientific term for heating metal and then rapidly cooling?
The scientific term for heating metal and then rapidly cooling it is "quenching." This process helps to alter the metal's physical properties, such as hardness and strength, by inducing a rapid transformation within its atomic structure.
Can the tectonic plates move rapidly?
They cant unless there was some random intense heating of the entire planet. As tectonic plates move because of the heating by the lava the lava would have to heat up intensely.
Why do the turn indicator lights flash rapidly in a 2005 town car?
one or more bulbs for the turn signal have burned out....try replacing the bulbs
How do you form a supersaturated solution?
Most often, by preparing a saturated solution of a substance in a solvent in which the solubility of the substance increases with temperature, then lowering the temperature while taking care to avoid agitation of or the intrusion of solids into the solution.
How do you stop your indicator from blinking rapidly in a 1999 Asto van?
What indicator are you talking about? Turn signal, emergency flasher, check engine light, abs light, oil light, temp light, alt light, etc. We can't read your mind.
