What else can I help you with?
What color is calcium phosphate?
Calcium phosphate is typically white in color.
Is calcium reactive with air?
Yes. Calcium will quickly form a coating of calcium oxide on contact with air.
In a reaction between sodium sulfate and calcium chloride what is the name of the precipitate formed and what colour is it?
the precipitate is calcium sulfate (CaSO4) and its white in color
What reacts with water to give a white alkaline solid?
Calcium oxide (CaO) reacts with water to give a white alkaline solid called calcium hydroxide (Ca(OH)2).
What happens when you touch calcium metal?
Sensory nerves in your finger trigger minute electrical impulses which travel to your brain. Your brain then interprets those impulses as one thing or another and you say, "Hmm, that's what calcium metal feels like."
What color is calcium in solid form?
Calcium in its pure solid form appears as a silvery-white metal. However, when exposed to air, it quickly forms a dull gray oxide and nitride coating.
What is the white coating in the kettle?
The white coating in a kettle is likely limescale, which is a deposit of calcium carbonate. It forms when hard water is boiled, leaving behind minerals on the kettle's surface. Regular descaling with vinegar or a commercial descaler can help remove this buildup.
Why does not wall imidiately acquire white colour when a coating of slaked lime is applied?
As slaked lime is of calcium hydro oxide it takes time. when heat react with calcium hydro oxide the water of calcium get evaporated it become quick lime (calcium carbonate). as the water evaporated the carbon dioxide get a chance to react with calcium carbonate and forms white colour.....

What is the appearance of calcium in its pure form at room temperature?
Calcium is a solid, soft dull grey metal at room temperature :)
What is the use of calcium?
Calcium makes bones and teeth strong as it is like the enamel coating your teeth and bones.
What is this white outer coating of the eye called?
The white outer coating on teeth is called enamel.
Why does not a wall immediately acquire a white colour when a coating of slaked lime is applied on it?
as slaked lime is of calcium hydro oxide it takes time. when heat react with calcium hydro oxide the water of calcium get evaporated it become quick lime (calcium carbonate). as the water evaporated the carbon dioxide get a chance to react with calcium carbonate and forms white colour
Why egg does not become hard in freezers?
Because egg has calcium coating
What is the theoretical reasons in using Ammonium thiosulfate Dipropylene Glycol and Calcium sulfate to clean the coating mixture of Calcium carbonate from Paper Notes?
The theoretical reason for using Ammonium thiosulfate, Dipropylene Glycol, and Calcium sulfate to clean the coating mixture of Calcium carbonate from Paper Notes is their ability to be used as wetting agents.
What is the theoretical reasons in using use Ammonium thiosulfate Dipropylene Glycol and Calcium sulfate to clean the coating mixture of Calcium carbonate from Paper Notes?
The theoretical reasons for using Ammonium thiosulfate, Dipropylene Glycol, and Calcium sulfate to clean the coating mixture of Calcium carbonate from Paper Notes is because they are wetting agents.
What is an example of a chemical property of the element calcium?
In contact with air, calcium develops an oxide and nitride coating, which protects it from further corrosion.
What color is calcium phosphate?
Calcium phosphate is typically white in color.
