Worked Solution & Example Answer:a) Distinguish between a concentrated and a dilute solution? (3) A pupil investigated the effect of temperature on the solubility of the salt ammonium chloride in water - Junior Cycle Science - Question Question 1 - 2007

Step 1

Distinguish between a concentrated and a dilute solution?

Answer

A concentrated solution contains a lot of solute in a small amount of solvent (water). In contrast, a dilute solution contains a small amount of solute in a large volume of solvent (water). Concentrated solutions can often be made dilute by adding more solvent.

Step 2

Plot a graph of solubility against temperature in the grid below.

Answer

To plot the graph:

  1. Start by selecting suitable scales for both axes; for example, the temperature (°C) can range from 0 to 100 on the x-axis, and the solubility (g/100 g water) can range from 0 to 80 on the y-axis.
  2. Plot the points given in the table:
    • (0, 29)
    • (20, 37)
    • (40, 46)
    • (60, 55)
    • (80, 66)
    • (100, 77)
  3. Connect the points with a smooth line to visualize the trend in solubility with temperature.

Step 3

Use the graph to estimate the solubility of ammonium chloride at 70 °C.

Answer

From the graph, estimate the solubility at 70 °C, which appears to be around 61 g/100 g water. Note that this estimate allows for slight variations, considering the scale.

Step 4

What conclusion about the solubility of ammonium chloride can be drawn from analysis of the graph?

Answer

The solubility of ammonium chloride in water increases as the temperature rises. This indicates that higher temperatures enhance the solubility of this salt in water.
