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.
What color does calcium burn in a flame test?
orange I disagree - calcium burns Red I disagree with you're answer^ whoever said red... while it is true that calcium burns red, we are talking about a binary compound, not a single element. calcium chloride burns orange. You are being too general. Calcium Chloride burns a deep orange with a slightly lighter orange core. Just saying orange is not enough. Just tried it in my lab - the main color is Red -sorry It depends on the purity of the salt and the amount of organic particles present.
What element emits a yellow light?
A better question would be "which elements burn red", as more than one element burns red. Lithium chloride burns red, calcium chloride burnds a red-orange, and strontium chloride burns bright red.
If Ammonium chloride is heated with calcium hydroxide the products formed are ammonia water and calcium chloride Balance this equation?
2NH4Cl + Ca(OH)2 >> CaCl2 + 2NH3 + 2H2O When ammonia chloride is heated with calcium hydroxide, ammonia gas is released. Ammonia gas is less dense than air so it is collected in an upside down test tube, by the downward displacement of air. The water formed is often seen as droplets on the side of the test tube. the ammonia gas causes the damp red litmus to change to blue because a solution of ammonia gas is alkaline.
When Litmus paper when added to calcium oxide and water?
When litmus paper is added to calcium oxide and water, it will turn blue due to the formation of calcium hydroxide, which is a basic solution. Calcium oxide reacts with water to form calcium hydroxide, releasing heat in the process.
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 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.
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.
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!
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.
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.
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 color flame do you get when you burn calcium chloride?
Calcium Chloride burns a deep orange with a slightly lighter orange core and has a light red glow at the top. The colour calcium chloride burns is described as brick red.
What colour does calcium chloride turn into when burnt?
brick red It is not a burning but a heating process.
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 is responsible for the red color in calcium chloride?
The metal - calcium (spectral lines)
What is the flame test for calcium chloride?
When calcium chloride is subjected to a flame test, it produces an orange-red flame. This color is due to the presence of calcium in the compound, which emits that specific wavelength of light when heated.
