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 colour does pink cobalt chloride paper turn in water?
Pink cobalt chloride paper will turn blue when exposed to water. Cobalt chloride is a chemical compound that changes color based on the amount of water present, with pink indicating a dry condition and blue indicating the presence of water.
What colour does litmus paper turn in sodium chloride acid?
- sodium chloride is not an acid - in an acid solution the blue litmus paper become red
What colour will sodium chloride turn when dissolved in ethanol water and chloroform?
Sodium chloride will not change color when dissolved in ethanol, water, or chloroform. It will form a clear solution in each solvent because NaCl is a colorless salt that does not have any inherent color.
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 colour does copper chloride turn in Universal indicator?
Bronze
What colour does blue copper chloride turn when moistened?
A darker shade of blue.
How could you tell if an unkown substance is sodium chloride or calcium carbonate?
Add dilute hydrochloric acid to both. There will be no reaction with the sodium chloride but the calcium chloride will effervesce and give off carbon dioxide which will turn lime-water milky.
Will the colour of copper turns to green due to overexposure to sodium chloride?
Copper will turn green when it's exposed to sodium chloride or salt.
How do you fry sausage?
Broiling is the same as grilling, not too hot, turn frequntly until a nice brown colour, not burnt.
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 colour will limewater turn if carbon dioxide is added?
Limewater will turn milky white when carbon dioxide is added to it due to the formation of calcium carbonate.
Does salt pepper sugar calcium chloride green tea and milk mixed together turn purple?
Who knows? Why don't you go find out!

What color will a cobalt chloride paper turn into when there is water vapor?
A cobalt chloride paper will turn pink when exposed to water vapor. This color change is due to the cobalt chloride reacting with the water vapor to form pink cobalt chloride hexahydrate.
Will damp cobalt chloride turn back blue once dried?
Solid Cobalt chloride crystals are pink when hydrated with water. If you heat the crystal, the water of crystallisation in the crystals will evaporate, leaving you with solid anhydrous cobalt chloride crystals which are blue in colour.
