ice. ice

Ice Ice is solid, crystalline water. Its melting point at a pressure of one atmosphere is m. The drawing below shows the structure of ice. The regular crystalline structure means that frozen water can take on patterns like those we see in snowflakes.
Ice is less dense than water and floats on it.

Hydrogen bonds


immiscible
non-miscible

Not married. When two liquids do not mix together, but rather form two layers: one liquid on top of the other, it is described
The two questions are that they are not married.

Two unmixed liquids
Less dense liquid
A denser liquid
A mixture of two mixed liquids

Perhaps one of the liquids is polar, such as water, and the other is nonpolar, such as ether. Two liquids mix

Less dense liquid
A denser liquid
faucet -

Two polar liquids are completely miscible, such as water and ethanol, and so are two nonpolar liquids, such as ether and tetrachloromethane. Can be separated
liquids using a separating funnel.

indicator
indicateur m

Indicator Indicator is a substance that changes color when conditions change. For example, litmus is red in an acidic solution and blue in an alkaline solution. It can be used to indicate the end point of a reaction. Indicators are useful in acid base titrations, as their colors differ when the pHs are different. They are also used in titration between metal ions and complex electrolytes. universal indicator
See complex ions.


inert gases
gaz mpl rares

Inert gases. See noble gases.


inorganic chemistry
chimie f organic

Inorganic chemistry. Inorganic chemistry is concerned with the non-organic aspects of chemistry, i.e. the elements and their compounds. This includes carbon and its oxides, carbonates of metals, and hydrogen carbonates, but excludes all organic compounds, such as alcohols, esters, ethers, and hydrocarbons. Etc. . hydrocarbons


insoluble
insoluble

Unsolvable. A substance that does not dissolve in a solvent.


insulator
isolant m

Insulator is a poor conductor of heat
And electricity both.
Non-metallic elements are usually insulators, as well
Most compounds are polymers, except graphite.

Examples of effective insulators:
Expanded polystyrene.
Rubber.
Mineral wools, such as rock wool.
Glass fiber.


iodides
iodides mpl

Iodides are compounds of iodine and element
Another, such as:
Potassium iodide KI, hydrogen iodide HI


iodine(I2)
iode m

He would like. No shiny gray metal. It is a halogen and has a diatomic molecular structure. Iodine is extracted from sodium iodate (Nala (V)) and a small amount of seaweed.
Silver iodide is used in photographic emulsions.

The human body needs 0.07 mg of iodine daily. The body uses it mainly to produce the hormone thyroxine. Potassium iodide is often added to table salt to provide the body's need for it.

Iodine reacts directly with some metals to form iodides, and it also reacts with hydrogen and chlorine to form [HI] and [ICI].
The vapor of this element is purple in color, and it is suffocating and caustic.
