(a)
Interpretation:
The product shown in the image (a) should be classified into solution, colloid or heterogeneous mixture.
Concept introduction:
The solution is defined as usually a homogenous mixture of two liquids whose particle size is less than
The colloids are the class of mixtures that have particles size much greater than the solutions. They can be clearly distinguished because of the presence of particles that constitute the dispersed phase of the colloidal systems and render them opaque. Butter milk is an example of colloids. There are various subcategories of colloids such as sol, foam, aerosol, emulsions. The particle size of colloids lies in the range of
The heterogeneous mixtures are essentially those mixtures that have non-uniform composition. The average particle size of heterogeneous mixture or suspension is more than

Interpretation:
The image (b) should be classified into either solution colloid or suspension on the basis of its appearance.

- Classify each of the following solutions as saturated, unsaturated, or supersaturated based on the following observations made after adding a small piece of solid solute to the solution. a. The added solute rapidly dissolves. b. The added solute falls to the bottom of the container where it remains without any decrease in size. c. The added solute falls to the bottom of the container where it decreases in size for several hours and thereafter its size remains constant. d. The added solute causes the production of a large amount of solid white crystals.arrow_forwardRefer to Figure 13.10 ( Sec. 13-4b) to determine whether these situations would result in an unsaturated, saturated, or supersaturated solution. 120. g RbCl is added to 100. g H2O at 50 °C. 30. g KCl is dissolved in 100. g H2O at 70 °C. 20. g NaCl is dissolved in 50. g H2O at 60 °C. Figure 13.10 Solubility of ionic compounds versus temperature.arrow_forwardA patient has a “cholesterol count” of 214. Like manyblood-chemistry measurements,this result is measured inunits of milligrams per deciliter (mgdL1). Determine the molar concentration of cholesterol inthis patient’s blood, taking the molar mass of cholesterolto be 386.64gmol1. Estimate the molality of cholesterol in the patient’sblood. If 214 is a typical cholesterol reading among men inthe United States, determine the volume of such bloodrequired to furnish 8.10 g of cholesterol.arrow_forward
