What happens when silver exposed to air?
Tarnish.
What happens to the weight of sodium chloride when it is exposed to air?
When sodium chloride is exposed to air, it can absorb moisture from the air, causing it to become damp or dissolve slightly. This can increase its weight due to the addition of water molecules.

Why do silver articles become black after sometime when exposed to air?
The silver exposed to air combines with oxygen in the air to form silver oxide which is black.
What happens to Calcium chloride in air?
When exposed to air, calcium chloride can absorb moisture and become hydrated, forming a white, powdery substance. It is hygroscopic, meaning it has a strong affinity for water molecules in the air. This property allows calcium chloride to be used as a desiccant to remove excess moisture from the air.

What happens when silver is exposed to air?
Silver reacts with sulfur compounds in the air to form a black tarnish layer called silver sulfide. This tarnish layer can be easily wiped off with a polishing cloth or a chemical cleaner to restore the silver's shine.
What happens when anhydrous CACL2 is exposed to air?
Anhydrous CaCl2 (calcium chloride) is hygroscopic, meaning it absorbs water vapor from the air. When exposed to air, it will quickly attract moisture and form hydrated CaCl2, which appears as a damp or liquid solution.
What is the rusting of silver?
The rusting of silver is not technically "rusting," as rust is specific to iron. Silver does not rust, but it can tarnish when exposed to air and sulfur compounds, forming a dark layer on the surface. This tarnish can be removed by polishing the silver.
Why does the chloride of lime gradually lose its chlorine when kept exposed to air?
Chloride of lime, or calcium hypochlorite, gradually loses its chlorine when exposed to air due to oxidation. The chlorine in chloride of lime reacts with oxygen in the air to form oxygen gas, reducing the chlorine content in the compound over time.
What is calciums appearance?
it is a silver substance.and has grayish white when exposed to air.
What happens when silver is exposed to sunlight?
When light shines on the silver chloride/albumin emulsion the redox reaction happens more quickly than it does in the dark. Imagine now a sensitized sheet of paper, half of which is exposed to bright sunlight and the other half of which is covered up with an opaque card. The silver ions in the exposed area will be reduced to black metallic silver in a matter of minutes; the silver ion under the card will remain colorless or white. Imagine now that you remove the opaque card; what will you see? The half of the paper that was in the light will be black and the half that was in the dark will be white. This reversal of light and dark is referred to as a negative image. But as soon as you remove the opaque card from the sensitized paper, the formerly unexposed white half will begin to turn black. In order to fix the image, we need to remove the light-sensitive silver chloride. Just washing it in water won't do the trick because silver chloride is insoluble in water. The earliest photographic fixer consisted simply of a concentrated solution of sodium chloride, ordinary table salt: While certainly convenient, this reaction does not go very far; only some of the silver chloride is dissolved and the rest remains on the paper. More effective than salt is ammonia.
