Not usually; a decomposition reaction is when you start with a single reactant and end up with two or more products. In some instances, you may have a salt (a metal bonded to a nonmetal), but this is not guaranteed.
The one reaction type that will always result in a salt being formed is a neutralization reaction, or an acid-base reaction. These reactions start with an acid and a base and result in a salt and water being formed.
Technically, it's neither. What actually happens is dissociation, where the compound separates into its constituent ions. The sodium and chloride ions are freely floating in the water, which makes the solution electrolytic, but no new substance has been formed. In fact, if the water is evaporated or boiled away, the salt will recombine.
This is a function of water's polarity (difference in electrical charge across the length of a water molecule,) which allows it to dissociate alkali halides and many other ionic compounds.
2NaCl->2Na +Cl2
So two molecules of sodium chloride ( table salt ) decompose into 2 atoms of sodium and one molecule of chlorine gas.
Salt is decomposed by electrolysis.
Electric curry
Salt is dissociated in water.
Yes. A salt is an ionic compound and so dissolving (or hydrolyzing) it is a chemical reaction. An example with sodium chloride (table salt): NaCl (solid) -> Na+ + Cl- The charges on the products indicate that they are aqueous (in solution). Since the reactant breaks apart into it's products, this is a dissociation reaction.
sodium sulphate ( na2so4) it is a neutralisation reaction in which base + acid = salt + water it falls in the category of double decomposition reaction
Table salt is a compound formed by reaction between sodium and chlorine.
This reaction is called neutralization; the products are a salt and water.
Salt and water
It always ends in a salt and water. The salt is not always NaCl (NaCl is table salt) another example is NaHSO4 (Sodium Bisulfate)
The products of a neutralization reaction are a salt and water.
The products of a neutralization reaction are a salt and water.
Water and a corresponding salt.
What is salt?Salt is a chemical compound made up of sodium (Na) and chloride (Cl), or NaCl.
Yes. A salt is an ionic compound and so dissolving (or hydrolyzing) it is a chemical reaction. An example with sodium chloride (table salt): NaCl (solid) -> Na+ + Cl- The charges on the products indicate that they are aqueous (in solution). Since the reactant breaks apart into it's products, this is a dissociation reaction.
Sodium Cloride
sodium sulphate ( na2so4) it is a neutralisation reaction in which base + acid = salt + water it falls in the category of double decomposition reaction
The reaction is different for each salt: melting, thermal decomposition, explosion etc.
if you mean epsom salts (magnesium sulfate) then heating it will result in a decomposition reaction, where magnesium oxide (s) and sulfur trioxide (g) is formed. The decomposition reaction is therefore a chemical change.
The products of neutralization reaction are water and a salt.
Table salt is a compound formed by reaction between sodium and chlorine.
