Rocawear has clothing lines and accessories for men, women and children.Its main funders currently are Mareed Clothing Line. Salts can also form if solutions of different salts are mixed, their ions recombine, and the new salt is insoluble and precipitates (see: Solubility equilibrium). Rocawear is an urban clothing label created in 1999 by Damon Dash & Jay-Z, heads of the hip hop label Roc-a-Fella Records. Salts are formed by a chemical reaction between:. Common salt-forming anions (and the name of the parent acids in parentheses) are:. Common salt-forming cations are:.
chloride or acetate). sodium salt or ammonium salt) or by the name of the anion (e.g. Salts are often referred to only by the name of the cation (e.g. chloride or acetate).
sodium or ammonium) followed by the name of the anion (e.g. The name of a salt starts with the name of the cation (e.g. ammonium salts like ammonia). acetates like acetic acid (vinegar), cyanides like hydrogen cyanide (almonds)) or the base (e.g.
Pure salts are odorless, while impure salts may smell after the acid (e.g. salty (sodium chloride), sweet (lead diacetate), sour (potassium bitartrate), bitter (magnesium sulfate), and umami or savory (monosodium glutamate). Different salts can elicit all five basic tastes, i.e. Most minerals and inorganic pigments as well as many synthetic organic dyes are salts.
yellow (sodium chromate), orange (sodium dichromate), red (mercury sulfide), mauve (cobalt dichloride hexahydrate), blue (copper sulfate pentahydrate, ferric hexacyanoferrate), green (nickel oxide), colorless (magnesium sulfate), white (titanium dioxide), and black (manganese dioxide). Salts exist in all different colors, e.g. Salts can be clear and transparent (sodium chloride), opaque (titanium dioxide), and even metallic and lustrous (iron disulfide).
Inorganic salts usually have a low hardness and a low compressibility, similar to edible salt. However, there exist salts that are liquid at room temperature, so-called ionic liquids. Salts are usually solid crystals with a relatively high melting point. After the water dried, the salt was left, which was collected and sold.
The Phoenicians harvested the salt by flooding plains of land with sea water, then leaving the plains to dry. The Phoenicians were victims of their success and as a result of harvesting the salt from the sea, the value of salt depreciated. They sold it to other civilisations and most of the time it cost more than gold. The Phoenicians (modern day Lebanese) were the first people to harvest salt from the sea.
Salt was also given to the parents of the fiancé in marriage until the 8th century. Payments to Roman workers were made in salt. In Ancient Rome, salt started to be used as currency originating the current Latin-derivative term salary. Salt was very valuable and used to conserve foods.
in Egypt, Greece and Rome. The first registers of salt use were at 4000 B.C. . It can also refer to natron.
Impure salt is a name for salt which has lost its saltiness. Salts that contain a hydroxide ion are basic salts and salts that contain a hydrogen ion are acid salts. Normal salt is salt that does not contain a hydroxide ion (OH-) or a hydrogen ion (H+). Therefore their salt content is given for the respective ions.
Mixtures of many different ions in solution like in the cytoplasm of cells, in blood, urine, plant saps, and mineral waters usually do not form defined salts after evaporation of the water. Zwitterions are salts that contain an anionic center and a cationic center in the same molecule, examples are the amino acids, many metabolites, peptides, and proteins. Electrolytes as well as molten salts conduct electricity. Solutions of salts in water are called electrolytes.
These ions can be inorganic (Cl-) as well as organic (CH3-COO-) and monoatomic (F-) as well as polyatomic ions (SO42-). In chemistry, salt is a term used for ionic compounds composed of positively charged cations and negatively charged anions, so that the product is neutral and without a net charge. silting is the natural deposit of salt from sea water.
