It heats 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.
The reaction between phenol and calcium hydroxide results in the formation of calcium phenolate and water. The chemical equation for this reaction is: C6H5OH (phenol) + Ca(OH)2 (calcium hydroxide) → Ca(C6H5O)2 (calcium phenolate) + H2O (water)
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.
The ferric chloride test is used to detect the presence of phenolic compounds in a substance. It involves adding ferric chloride solution to the sample, and if phenolic compounds are present, a colored complex forms due to the formation of iron-phenol complexes. The intensity of the color change can be used to estimate the concentration of phenolic compounds in the sample.
The color of ferric chloride with salicylate is purple. This color change occurs when salicylate is added to a solution of ferric chloride, producing a complex between the two compounds that results in a purple color.
When baking soda (NaHCO3) reacts with calcium chloride (CaCl2), it forms calcium carbonate (CaCO3), water (H2O), and carbon dioxide (CO2). Phenol red is a pH indicator that changes color based on the pH of the solution, and it does not participate in the chemical reaction.
When Calcium chloride reacts with phenol red and baking soda, it will generate carbon dioxide gas. This reaction causes the phenol red to change color – it will turn from red to yellow as the pH decreases due to the formation of carbonic acid.
when you mix all three you get a chemical change. you also get heat and bubbles witch indicates that there is gas!
The reaction between phenol red, calcium chloride, and baking soda is endothermic. The mixture will absorb heat from its surroundings as it undergoes the reaction, causing the temperature of the mixture to decrease.

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.
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.
"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.
Swallowing phenol red indicator solution can be harmful, as it is a chemical compound. It may cause irritation or burning in the mouth, throat, and stomach. It is important to seek medical attention if ingestion occurs.
The reaction between phenol and calcium hydroxide results in the formation of calcium phenolate and water. The chemical equation for this reaction is: C6H5OH (phenol) + Ca(OH)2 (calcium hydroxide) → Ca(C6H5O)2 (calcium phenolate) + H2O (water)
Normal ferric chloride gives a positive test for phenol as it forms a violet complex with it. This can lead to false positives in other compounds that also react with ferric chloride, making it unreliable for detecting phenol specifically. Instead, a modified version called FeCl3/KI reagent is commonly used for phenol detection as it gives a distinct green color with phenol, allowing for more accurate and specific results.
