Q2.Write the formula of the following:
a) sodium chloride
b) calcium chloride
c) magnesium chloride
d) sodium carbonate
e) magnesium sulphate
Answers
Sodium chloride is the chemical name for salt. Sodium is an electrolyte that regulates the amount of water in your body. Sodium also plays a part in nerve impulses and muscle contractions. Sodium chloride is used to treat or prevent sodium loss caused by dehydration, excessive sweating, or other causes.
Formula: NaCl
IUPAC ID: Sodium chloride
Molar mass: 58.44 g/mol
Melting point: 801 °C
Density: 2.16 g/cm³
Soluble in: Water, Ammonia, Methanol, Glycerol, Formic acid, Propylene glycol, Formamide
Calcium chloride is an inorganic compound, a salt with the chemical formula CaCl2. It is a white coloured crystalline solid at room temperature, and it is highly soluble in water. It can be created by neutralising hydrochloric acid with calcium hydroxide.
Magnesium chloride is the name for the chemical compounds with the formulas MgCl2 and its various hydrates MgCl2(H2O)x. These salts are typical ionic halides, being highly soluble in water. The hydrated magnesium chloride can be extracted from brine or sea water.
Magnesium sulfate is a magnesium salt having sulfate as the counterion. It has a role as an anticonvulsant, a cardiovascular drug, a calcium channel blocker, an anaesthetic, a tocolytic agent, an anti-arrhythmia drug, an analgesic and a fertilizer. It is a magnesium salt and a metal sulfate.
