Terms

Question 1

Hydrogen Bond

Answer 1

bond between partially positive hydrogen atoms and partially negative atoms, and it’s weak

Question 2

Acid

Answer 2

gives H+, produces (H3O) in water

Question 3

Base

Answer 3

recieves H+, produces (OH-) in water

Question 4

Amphiprotic

Answer 4

can act as an acid or base, like water

Question 5

Self Ionization of Water

Answer 5

very rare in pure water, where water dissociates into OH and H3O on its own

Question 6

Acid-Base tritration

Answer 6

a lab technique to find the concentration of an acid or base by adding a solution until a reaction completes

Question 7

More H = Lower pH, and Less H = Higher pH

Answer 7

True

Question 8

Dissociation/Ionization

Answer 8

process of a compound breaking apart in water

Question 9

Neutralization

Answer 9

chemical reaction between an acid and base that results in the formation of water and salt

Question 10

Buffers:

Answer 10

• resist changes in pH, by neutralizing small amounts of an added acid or base
• contain a weak acid & conjugate base, or a weak base & conjugate acid

Question 11

Condensation

Answer 11

gas to liquid

Question 12

Hydrophilic

Answer 12

loves water

Question 13

Cohesion

Answer 13

water molecules attracted to other water molecules

Question 14

Adhesion

Answer 14

water molecules attraction to other molecules

Question 15

Surface Tension:

Answer 15

• at the surface, molecules are being pulled by other molecules less because they are less surrounded so they cling to nearby molecules tighter, forming tension at the surface
• possible because of cohesion/hydrogen bonding
