At a <u>specified temperature</u>, the density of 10% common salt solution is <u>more than the </u><u>density</u><u> of fresh water</u> because compared to fresh water, salt water contains more substances. That substance would be salt, which <u>increases the mass</u> of water <u>without significantly increasing its volume</u>.
As density is given by the formula:
<h3>How does salt dissolve in water ?</h3>
The ionic link that held sodium and chloride ions together is broken when <u>water molecules</u> force the ions apart. The sodium and chloride atoms are <u>encircled by water molecules</u> after the salt compounds are separated. After that, the <u>salt dissolves</u> and forms a homogenous solution.
The reaction that takes place is :
<h3>How does dissolution of salts affect the density of a solution?</h3>
In case of a solid(solute) - liquid( solvent) reaction with <u>slight increase in mass </u>, with <u>no considerable increase in volume</u>, the overall <u>density of a solution increases</u>.
Therefore, if
ΔV ≈ 0
then, density ∝ mass
In case of salt solutions, the solute doesn't add much to volume, whereas<u> it increases the overall mass of a solution</u> considerably , therefore the <u>density</u> increases.
