Salt
Salt is chemically defined
as the neutral product
formed as a result of a
reaction between an acid
and an alkali.
Types of Salt
1.Table Salt
Table salt is one of the most commonly used
salts in the kitchen.
2.Kosher Salt
Kosher salt is a type of crystalline edible
salt, which is a coarser as compared to table
salt and has large-size grains.
3.Sea Salt
Sea salt is salt obtained by the evaporation
of sea water.
4. Sel Gris or Gray Salt
Sel gris or Gray salt is a courage grain
salt obtained from Brittany. It is an
unrefined sea salt that is light gray in color.
5. Fleur de Sel
This salt is also obtained from Guerande
region in Brittany, France and it’s name
means “flower of salts”. Just like gray salt,
this salt is also collected manually using
only wooden tools.
6. Hawaiian Sea Salt
Hawaiian Sea Salt is also known as alae,
this salt is obtained by adding alae, a volcanic
clay, to the sea salt. The volcanic clay being rich
in iron oxides, gives the salt a reddish tinge
along with an earthly flavor.
7. Rock Salt
Rock Salt differs from most other varieties
of salt for the fact that is mined from under the
earth and not obtained from sea water.
Properties
of Salt
Color
Potassium dichromate, a bright orange salt used
as a pigment. Salt can appear to be clear and
transparent (sodium chloride), opaque, and even
metallic and lustrous (iron disulfide). 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 powder.
Taste
Different salts can elicit all five basic tastes…
Example:
•Salty (sodium chloride)
•Sweet (lead diacetate)
•Sour (potassium bitartrate)
•Bitter (magnesium sulfate)
•Umami or Savory (monosodium glumate)
Odor
Salts of strong acids and strong bases (“strong
salts”) are non-volatile and odorless, whereas as salts
of either weak acids or weak bases (“weak salts”) may
smell after the conjugate acid (ex. Acetates like acetic
acid (vinegar) and cyanides like hydrogen cyanide
(almonds) or the conjugate base (ex. Ammonium salts
like ammonia) of the component ions. That slow,
partial decomposition is usually accelerated by the
presence of water, since hydrolysis is the other falf of
the reversible reaction equation of formation of weak
salts.
Solubility
Solubility, solubility of ionic compounds in water. Many ionic
compounds can be dissolved in water or other similar solvents. The
exact combination of ions involved makes each compound have a
unique solubility in any solvent. The solubility is dependent on how
well each ion interacts with the solvent, so there are certain patterns.
For example, all salts of sodium, potassium and ammonium are soluble
in water, as are all nitrates and many sulfates– barium sulfate, calcium
sulfate (sparingly soluble) and lead(II) sulfate are examples of
exceptions. However, ions that bind tightly to each other and form
highly stable lattices are less soluble, because it is harder for these
structures to break apart for the compounds to dissolve. For example,
most carbonate salts are not soluble in water, such as lead carbonate and
barium carbonate. Some soluble carbonate salts are: sodium carbonate,
potassium carbonate and ammonium carbonate.
Conductivity
Solid salts do not conduct
electricity. However, liquid salts
do. Moreover, solutions of salts
also conduct electricity
