Components of Solutions - Simplest type of solution – sugar water solution - Solute – substance dissolved in a solution a. Component of solution that is a lesser quantity b. Dissolved solute particles are too small to be seen c. Stays mixed unless conditions change - Solvent – dissolving medium in a solution - Solute – particle dimensions range from 0.01 – 1 nm Types of Solutions - Refer to page 396, table 13-1 for possible solute – solvent combinations - Alloys are solid solutions – atoms of two or more metals are uniformly mixed - Choosing proportions of each metal in an alloy – obtain desirable properties Suspensions - Suspension – particles in a solvent are so large that they settle out unless the mixture is constantly stirred or agitated

Unformatted text preview: -Gravity pulls large particles down-Particles in suspension can be separated from the heterogeneous mixtures by passing the mixture through the filter Colloids-Colloids – particles that are intermediate in size between those in solutions and suspension from mixtures known as colloidal dispersions-Formed between 1nm and 1000nm in diameter a. Ex. soil and water – water is still muddy because of colloidal particles If poured through filter, it would still be cloudy-Dispersed phase – colloidal particles-Dispersing medium – water-Emulsion – mayonnaise is an emulsion of oil droplets in water a.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
