Question

give two examples by which salt can be made​

Answer 1

Answer:

Many salts are commonly found and used in the home.

Sodium Chloride. Table salt, or sodium chloride, is the ionic product of the combination of lye, or sodium hydroxide, and hydrochloric acid. ...

Ammonium Dichlorate. ...

Magnesium Sulfate. ...

Sodium Bicarbonate.

Answer 2

Answer:

In chemistry, a salt is a solid chemical compound consisting of an ionic assembly of cations and anions.[1] Salts are composed of related numbers of cations (positively charged ions) and anions (negative ions) so that the product is electrically neutral (without a net charge). These component ions can be inorganic, such as chloride (Cl−), or organic, such as acetate (CH

3CO−

2); and can be monatomic, such as fluoride (F−), or polyatomic, such as sulfate (SO2−

4).

Types of salts

Salts can be classified in a variety of ways. Salts that produce hydroxide ions when dissolved in water are called alkali salts. Salts that produce acidic solutions are acid salts. Neutral salts are those salts that are neither acidic nor basic. Zwitterions contain an anionic and a cationic centres in the same molecule, but are not considered to be salts. Examples of zwitterions include amino acids, many metabolites, peptides, and proteins.[2]

Color

Edit

Solid salts tend to be transparent as illustrated by sodium chloride. In many cases, the apparent opacity or transparency are only related to the difference in size of the individual monocrystals. Since light reflects from the grain boundaries (boundaries between crystallites), larger crystals tend to be transparent, while the polycrystalline aggregates look like white powders.

Salts exist in many different colors, which arise either from the anions or cations. For example:

sodium chromate is yellow by virtue of the chromate ion

potassium dichromate is orange by virtue of the dichromate ion

cobalt nitrate is red owing to the chromophore of hydrated cobalt(II) ([Co(H2O)6]2+).

copper sulfate is blue because of the copper(II) chromophore

potassium permanganate has the violet color of permanganate anion.

nickel chloride is typically green of [NiCl2(H2O)4]

sodium chloride, magnesium sulfate heptahydrate are colorless or white because the constituent cations and anions do not absorb in the visible part of the spectrum

Few minerals are salts because they would be solubilized by water. Similarly inorganic pigments tend not to be salts, because insolubility is required for fastness. Some organic dyes are salts, but they are virtually insoluble in water.
