1. The solubility of a gaseous solute in water is by an increase in pressure. Increased decreased not affected 2. A supersaturated solution may be prepared by slowly cooling down a solution saturated at an elevated temperature. TRUE FALSE 3. A dilution is a solution made by adding a solvent to a supersaturated solution. TRUE FALSE 4. When sugar & water are mixed, a clear liquid results. In this scenario, the sugar is considered a Solute Solution Solvent All of...
Concentrations of solute in solvent, whether in saturated solutions or not, can be expressed in many ways (molarity, molality, ppm, percent by mass, etc.). Molarity = moles of solute / liter of solution molality = moles of solute / kg of solvent ppm = mg solute / liter of solution ppb = microgram of solute / liter of solution %-by-mass = (grams of solute / grams of solution) x 100% To convert from %-by-mass to Molarity, assume 100g of solution,...
