The document discusses key concepts related to solutions and solubility. It provides examples to illustrate different types of solutions, including solutions with varying amounts of solute and solvent. Examples are given to demonstrate solutions where the substances are in liquid, gas, or solid form. Key terms are defined, such as soluble, insoluble, and properties that depend on solution concentration. Safety guidance is provided at the end regarding antifreeze mixtures.
18. HAPPENS WITH THE ADDITION OF A SOLUTE TO A
SOLVENT – IN OTHER WORDS “HARDER” TO FREEZE
-EXAMPLE - OCEAN FREEZES AT 28 DEGREES, NOT 32
19. HAPPENS WITH THE ADDITION OF A SOLUTE TO A
SOLVENT – IN OTHER WORDS “HARDER” TO BOIL
-EXAMPLE - OCEAN BOILS AT 216, NOT 212DEGREES
20. WORD USED TO DESCRIBE THE FACT THAT SOMETHING
DISSOLVES IN SOMETHING ELSE
-EXAMPLE - SALT IS SOLUBLE IN WATER
21. WORD USED TO DESCRIBE THE FACT THAT SOMETHING WILL
NOT DISSOLVE IN SOMETHING ELSE BARELY AT ALL
-EXAMPLE - GOLD IS INSOLUBLE WATER
22. PROPERTIES THAT DEPEND ON SOLUTION
CONCENTRATION.
-EXAMPLE - FP DEPRESSION, BP ELEVATION
23. Water freezes at 32degF, antifreeze freezes at
14deg F, a 50:50 mixture of water and antifreeze
freezes at -28deg F. In other words, DON’T USE
PURE ANTIFREEZE!
