Question

When salt is dissolved in water____________
A.The particles of water get into the spaces between particles of salt
B.The particles of salt get into the spaces between particles of water
C.The particles of salt sit on the top of the particles of water
D.The particles of water sit on the top of particles of salt

Answer 1

Hint: A salt is an ionic compound that contains a cation which is a base and an anion which is an acid. In seawater, salts are present in large quantities and it is the main mineral constituent. It is extremely important for animal life and saltiness is one of the basic human tastes. It is formed along with water when there is a reaction between acids and bases. For example- $NaCl$, $CuC{l_2}$ etc. In general, we can say that
$Acid + Base \to Salt + Water$

Complete step by step answer:
The four fundamental characteristics of matter are:
1.Particles of matter are much smaller in size.
2.Particles of matter have spaces between them.
3.Particles of matter move constantly.
4.Particles of matter are attracted to each other.

The second fundamental characteristic of matter says that particles of matter have spaces between them so when we dissolve salt or sugar, its particles get into the spaces between the particles of water due to which the volume of the water remains the same.

Therefore we can say that the particles of salt get into the spaces between particles of water when the salt is dissolved into the water.

So, the correct answer is Option B .

Note: The types of salt are:

1.Acidic salt: - Acidic salts are the salts that are formed by the partial neutralization of a diprotic or a polyprotic acid. These salts contain ionizable ${H^ + }$ ions along with another cation. Examples of acidic salts are $NaHS{O_4}$, $K{H_2}P{O_4}$etc.

2.Basic salt: - Basic salts are the salts formed by the partial neutralization of a strong base by a weak acid. Examples of these type of salts are $\left( {2PbC{O_3}.Pb{{\left( {OH} \right)}_2}} \right)$ which is commonly known as White Lead.

3.Double salt: - Double salts are the salts that contain more than one cation or anion. They are prepared by the combination of two different salts crystallized in the same lattice. For example- $\left( {KNa{C_4}{H_4}{O_6}.4{H_2}O} \right)$ which is commonly known as Rochelle salt.
Mixed salts: - Mixed salts are the salts that contain a fixed proportion of two salts, often sharing a common cation or anion. For example- $CaOC{l_2}$
