Why calcium chloride or silica is placed in desiccatorswhy should it be dried occasionally?
Calcium chloride or silica gel is placed in desiccators to absorb any moisture present in the air, creating a dry environment for storing moisture-sensitive materials. These desiccants need to be dried occasionally because they reach a saturation point where they can no longer absorb moisture effectively, and drying them renews their moisture-absorbing capabilities for continued use.

Does metal rust when you put it in calcium chloride?
No, metal does not rust when placed in calcium chloride. This is because calcium chloride is a desiccant that absorbs moisture from the environment, preventing the formation of rust on the metal surface.
Is calcium chloride soluble or insoluble in water?
Calcium chloride is soluble in water. It ionizes into calcium ions (Ca2+) and chloride ions (Cl-) in solution.
What happens when Calcium Chloride is placed in water?
When Calcium Chloride is placed in water, it dissociates into its ions, Ca2+ and Cl-. These ions help increase the total ion concentration in the solution, making it a good source of calcium for certain applications like food preservation, road de-icing, and concrete setting. Additionally, the dissolution of Calcium Chloride in water is exothermic, which means it releases heat.
Why CaCl2 or silica is placed in desiccator Why should it be dried occasionally?
CaCl2 or silica gel is placed in a desiccator to absorb moisture from the air inside, keeping the contents of the desiccator dry. These desiccants need to be dried occasionally to regenerate their drying capacity by removing absorbed moisture, ensuring they can continue to maintain low humidity levels within the desiccator effectively.
Why calcium is placed after potassium?
The periodic table is arranged by atomic number, which is the number of protons in the nucleus of an atom. Potassium has an atomic number of 19, while calcium has an atomic number of 20. This is why calcium is placed after potassium in the periodic table.

Calcium chloride placed in Bunsen burner flame?
you would produce radon gas.

How much time one kg of Calcium Chloride to get fully liquidified if placed in open?
Impossible to calculate, even if temperature, ventilation rate, humidity and a description of the container was provided in the question.
Does calcium sink when placed in water?
Yes, calcium does sink in water
What phenomena will occur when silica gel and anhydrous CaCl2 are placed into corners of a vessel containing water vapours?
The water will be absorbed; calcium chloride being highly hygroscopic become after a period of time a solution. If silica gel was colored with cobalt chloride the color is changed after the water absorption.
Does limestone dissolved in acid?
YES!!! Limestone is an impure form of calcium carbonate. Calcium carbonate will react with acids to form the corresponding salt, water and carbon dioxide. e.g. CaCO3(s) + 2HCl(aq) = CaCl2(aq) + H2O(l) + CO2(g)

Why does a turkey wishbone turn rubber when placed in vinegar?
A turkey wishbone will turn to rubber when placed in vinegar because the vinegar dissolves the calcium. Calcium is what makes a bone hard.
