Chapter 21.2, Problem 11R

To determine

The precise concentration and relative concentration are to be compared and contrasted.

Answer to Problem 11R

Relative concentration can be defined as the ratio of concentration in medium to the concentration of reference medium.

Precise concentration is accurate value of concentration.

Explanation of Solution

Contrast:

Relative concentration is comparison of similar solutions with different concentration but precise concentration gives the exact value.

Compare:

Both the concentration that is relative and precise measure the concentration value of solute particles,in a particular type of solution at particular condition of temperature and pressure.

Conclusion:

Relative and precise concentration is used to measure the value of solute particles.
