How will Calcium chloride react with phenol red and baking soda?
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.
Does phenol red mixed with calcium chloride and baking soda turn out to be a exothermic or endothermic?
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.
What is the chemical equation when you mix baking soda calcium chloride and phenol red.?
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.
What happens when you add phenol red indicator to calcium chloride?
When phenol red indicator is added to calcium chloride, there won't be any specific chemical reaction between the two. Phenol red is commonly used as a pH indicator, changing color based on the acidity or alkalinity of a solution. However, since calcium chloride does not significantly affect the pH of a solution, the color of phenol red may not change in this case.
Baking Soda mixed with calcium chloride and phenol red solution chemicla or physical change?
It is a chemical change because it produces heat which is evidence that a chemical change has occured.
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 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.
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.
What is the chemical equation of the reaction between phenol and calcium hydroxide?
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)
Why normal ferric chloride is not used in detection of phenol?
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.
Does phenol red change baking soda to red?
Phenol red is a pH indicator that changes color in response to pH changes. It turns yellow in acidic conditions and red in basic conditions. When added to a solution containing baking soda (sodium bicarbonate), which is a basic substance, phenol red can turn red.
