Interpretation
The process how Aluminium sulfate used in municipal water treatment plants to remove undesirable particles should be explained.
Concept introduction
Like dissolves like principle: ‘Like dissolves like’ principle says that polar compounds including ionic compound should be more soluble in polar solvent. Likewise, non–polar compound should be more soluble in non–polar solvent.
Polar molecule: Polar molecules have large dipole moments.
Non-Polar molecules: Non-polar molecules have bonded atoms with similar electronegativity results to have zero dipole moments.
Saturated solution is the solution that contains maximum quantity of solute dissolved in the solvent. In the given volume of saturated solution amount of solute dissolved in the solvent called solubility. Unsaturated solution is the solution that contains less quantity of solute than saturated solution. Supersaturated solution contains more solute than solute present in the saturated solution.
Solubility is the quantity of solute (solid, liquid or gas) that will dissolve in a given amount of solvent (solid, liquid or gas) at definite temperature and pressure. Solubility depends on the physical and chemical property of solvent, solute and concentration of the solution.
Precipitation: It is the process in which involves separation of excess of solid present in supersaturated solution.

- What is the mole fraction of H 2 S O 4 in a solution containingthe percentage of sulfuric acid and water shownin Figure 14.25?arrow_forwardThe dispersed phase of a certain colloidal dispersion consists of spheres of diameter 1.0 102 nm. (a) What are the volume (V=43r2) and surface area (A = r2) of each sphere? (b) How many spheres are required to give a total volume of 1.0 cm3? What is the total surface area of these spheres in square meters?arrow_forwardA sample of water contains 0.010 ppm lead ions, Pb2+. (a) Calculate the mass of lead ions per liter in this solution.(Assume the density of the water solution is 1.0 g/mL.) (b) Calculate the mass fraction of lead in ppb.arrow_forward
- The solubility of ammonium formate, NH4CHO2, in 100. g of water is 102 g at 0 C and 546 g at 80 C. A solution is prepared by dissolving NH4CHO2 in 200. g of water until no more will dissolve at 80 C. The solution is then cooled to 0 C. What mass of NH4CHO2 precipitates? (Assume that no water evaporates and that the solution is not supersaturated.)arrow_forwardSodium chloride (NaCl) is commonly used to melt ice on roads during the winter. Calcium chloride (CaCl2) is sometimes used for this purpose too. Let us compare the effectiveness of equal masses of these two compounds in lowering the freezing point of water, by calculating the freezing point depression of solutions containing 200. g of each salt in 1.00 kg of water. (An advantage of CaCl2 is that it acts more quickly because it is hygroscopic, that is. it absorbs moisture from the air to give a solution and begin the process. A disadvantage is that this compound is more costly.)arrow_forward
