Why does phenol red and calcium chloride heat up?
I'm not completely sure, but it does have something to do with the water. When added to water the calcium chloride also heats up, so it's not about the phenol, but about the water and the reaction of the reactant dissolving that causes heat.
What is the chemical equation of the reaction between phenol and calcium hydroxide?
Calcium hydroxide, a base, will reaction with phenol, a weak acid in a neutralization reaction to give a salt (calcium phenoxide (Ca(PhO-)2) and water.
What are the products of a reaction between phenol and magnesium chloride?
Phenol is so weakly acidic that it cannot react with metals low in the electrochemical series. Also, phenol reacts only with Sodium metal and no other. Hence, it does not react with Magnesium at room temperature.
Why would vanillin test positive in a ferric chloride test?
It would test positive because there is a phenol group in vanillin.
What happens when bromine reacts with an phenol?
2 bromophenol, 4 bromophenol and hydrogen bromide are formed
How will Calcium chloride react with phenol red and baking soda?
CaCl2 will NOT react with phenol red (an weakly acidic pH-indicator) and baking soda HCO3- ions.

What happens when you mix calcium chloride phenol red and baking powder with water?
when you mix all three you get a chemical change. you also get heat and bubbles witch indicates that there is gas!
Does phenol red mixed with calcium chloride and baking soda turn out to be a exothermic or endothermic?
it results in a exothermic reaction
What happens when calcium chloride sodium bicarbonate and phenol red solution are mixed together?
Calcium Chloride and Sodium Bicarbonate turn pink, then turn yellow due to carbonic acid that is created. the mixture turns hot and gas is, about 10 seconds later the mixture stops producing gas and turns cold.
What happens if you swallow the phenol red indicator solution?
Your throat will be irritated and your voice will turn hoarse.
Does calcium chloride and water form hydrochloric acid?
No, they simply form a solution of calcium chloride. This is correct, but one should add that the solution heats up because of the exothermic process involved when water causes the calcium chloride crystals to dissolve; the calcium chloride is dissociated into calcium and chloride ions. However, the question is why does the solution test as an acid when phenol red is added? The red solution turns yellow indicating an excess of hydrogen (hydronium) ions. There is no adequate answer that I could find on the Internet.
What happened to phenol with Iron III chloride reagent?
"Addition of aqueous iron III chloride to a phenol gives a colored solution. Depending on the structure of the phenol, the color can vary from green to purple.
Why normal ferric chloride is not used in detection of phenol?
Normal solution of ferric chloride is acidic in nature and phenol is also acidic so neutral ferric chloride is more useful.
Does phenol red change baking soda to red?
Phenol red is a pH indicator. The baking soda is not changing color, but the phenol red is.
What is the Prepration of phenyl benzoate from phenol?
reacting a benzoyl chloride with a phenol to get an phenyl benzoate(ester).
What is the pH indicator in TSI agar?
Phenol Red
