Problem 36P

Refer to Figure 1 determine whether each of the given amounts of solid will completely dissolve in the given amount of water at the indicated temperature.

(a) 45.0 g CaCl2 in 105 g of water at 5 °C

(b) 15.0 g KClO3 in 115 g of water at 25 °C

(c) 50.0 g Pb(NO3)2 in 95.0 g of water at 10 °C

Problem 36P

Refer to Figure 1 determine whether each of the given amounts of solid will completely dissolve in the given amount of water at the indicated temperature.

(a) 45.0 g CaCl2 in 105 g of water at 5 °C

(b) 15.0 g KClO3 in 115 g of water at 25 °C

(c) 50.0 g Pb(NO3)2 in 95.0 g of water at 10 °C

Figure 1 Solubility of some ionic solids as a function of temperature

Solution: Here, we are going to identify if the given amounts of solid will dissolve completely in the given amount of water at the indicated temperature.

Step1:

Solubility of a substance is its maximum amount that can be dissolved in a specified amount of solvent. It depends upon the nature of solute and solvent as well as temperature and pressure.

Step2:

  1. From figure 1, it is clear that the solubility of CaCl2 at 5 oC is about 60 g per 100 g of water.

Thus, 45.0 g of  CaCl2 will dissolve completely in 105 g water at 5 oC.

     b)        From figure 1, it is clear that the solubility of KClO3 at 25 oC is about 8 g per 100 g of

water.

So, for dissolving 15.0 g of KClO3, amount of water required = (100/8) x 15 = 187 g

water

Thus, 15.0 g of  KClO3 will not dissolve in 115 g water at 25 oC.

    c)        From figure 1, it is clear that the solubility of Pb(NO3)2 at 10 oC is about 45 g per 100 g

of water.

Thus, 50.0 g of  Pb(NO3)2 will not dissolve in 95.0 g water at 10 oC.
