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.

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.

An aqueous solution is 20.0% by mass of sodium thiosulfate pentahydrate, Na, S2 O3-5H2O. What is the molarity of Na2 S2 O3 in this solution at 20°C? The density of this solution at 20°C is 1.173 g/mL. mol/L Molarity =

An aqueous solution has 0.0065 g of oxygen dissolved in 2.5 L of water. Calculate the dissolved oxygen concentration of this solution in parts per million. What mass of solute, in mg, is present in a 250 mL sample of potassium chloride solution with a concentration of 4.6 ppm? In some areas, drinking water is fluoridated to reduce tooth decay. The maximum acceptable concentration (MAC) of fluoride ions in drinking water is 1.50 ppm.In Dublin, California, a malfunction occurred in the fluoridation equipment caused fluoride levels to rise as high as 200 ppm. This resulted in many people becoming ill.During the malfunction, 639 kg of fluoride ions where injected into a storage tank of water. Given that the resulting concentration was 200 ppm, calculate the volume, in ML, of the water storage tank.

A student dissolves 2.6 g of aniline (C6H5NH₂) in 175. mL of a solvent with a density of 0.90 g/mL. The student notices that the volume of the solvent does not change when the aniline dissolves in it. Calculate the molarity and molality of the student's solution. Be sure each of your answer entries has the correct number of significant digits. molarity = 0 = molality 0 x10 00
