Question

What is concentration.... definition with a example.

Answer 1

hi your answer is

concentration is a term used when the amount of acid or base is more then Water that is percentage of water is less resulting into high dissociation of H+ and OH- ions.

example : 60% of HCL gas and 40% of water results in formation of concentrated hydrochloric acid.

Answer 2

In chemistry, concentration refers to the amount of a substance per defined space. Another definition is that concentration is the ratio of solute in a solution to either solvent or total solution. Concentration usually is expressed in terms of mass per unit volume. However, the solute concentration may also be expressed in moles or units of volume. Instead of volume, concentration may be per unit mass. While usually applied to chemical solutions, concentration may be calculated for any mixture.

Example:

If we add 68 g sugar and 272 g water to 160 g solution having concentration 20 %, find final concentration of this solution.
Solution:
Mass of solution is 160 g before addition sugar and water.
100 g solution includes 20 g sugar
160 g solution includes X g sugar
X=32 g sugar
Mass of solute after addition=32 + 68=100 g sugar
Mass of solution after addition=272 +68 + 160=500 g
500 g solution includes 100 g sugar
100 g solution includes X g sugar
X= 20 % is concentration of final solution.
