Solutions

Question 1

Solute

Answer 1

component being dissolved

Question 2

Solvent

Answer 2

dissolves other substances

Question 3

Solution

Answer 3

mix of 2+ substances

Question 4

Aqueous solution

Answer 4

when water is used as a solvent (ex: dissolving NaCl in H20

Question 5

High heat capacity

Answer 5

property of water. 212F to break hydrogen bonds. water in blood helps maintain homeostasis by moving heat

Question 6

High solubility

Answer 6

property of water. slight O- and H+ makes water attracted to most other molecules. able to break them up

Question 7

Lubrication

Answer 7

property of water. buffer btw joints & organs. little friction btw H2O molecules = less heat when joints/organs move around

Question 8

Colloid

Answer 8

large organic molecules

Question 9

Suspension

Answer 9

Visible difference between solvent (i.e. water) and solute (i.e. oil)

Question 10

Concentration

Answer 10

Ratio of solute to solvent

Question 11

Electrolytes

Answer 11

inorganic ions that conduct electricity in solutions. usually salts

Question 12

H+

Answer 12

Hydrogen Ion

Question 13

OH-

Answer 13

Hydroxide Ion

Question 14

Salt

Answer 14

Electrolyte whose Cation is not H+ and Anion is not OH-

Question 15

Acid

Answer 15

release H+ into solution. decreasing pH.

Question 16

Base

Answer 16

aka: alkaline. release OH- into solution. increasing pH

Question 17

pH scale levels

Answer 17

acid: 10-1 thru 10-6. alkaline/base: 10-8 thru 10-14. neutral 10-7 (water)
