7 C. Mixtures Variable combination of 2 or more pure substances. HeterogeneousHomogeneous
8 Tyndall Effect Disperses Light
9 C. Mixtures Solution homogeneous very small particles No Tyndall effect Tyndall Effect particles don’t settle EX: rubbing alcohol
10 C. Mixtures Colloid heterogeneous medium-sized particles Tyndall effect particles don’t settle EX: milk
11 C. Mixtures Suspension heterogeneous large particles particles settle EX:fresh-squeezed lemonade
12 C. Mixtures Examples: mayonnaise muddy water fog saltwater Italian salad dressing colloid suspension colloid solution suspension
