Answer 1

homogeneous mixture made of solute and solvent

Question 2

solute

Answer 2

smaller amount

Question 3

solvent

Answer 3

larger amount

Question 4

In an OH- bond, which has partial negative charge, and which has partial positive charge?

Answer 4

partial negative- oxygen

partial positive-hydrogen

Question 5

define hydration

what type of solution does hydration occur in?

Answer 5

process that diminishes attractions between positive and negative ions and keeps them in solution
ionic

Question 6

when solute and solvent forms a solution, energy is___

Answer 6

released

Question 7

electrolytes

Answer 7

seperate into ions and conduct electricity when dissolved in water

Question 8

nonelectrolyte

Answer 8

dissolve as molecules, don’t conduct electricity

Question 9

dissociation

Answer 9

process of solutes dissolving to produce ions

Question 10

strong electrolyte

Answer 10

100% dissociation

Question 11

weak electrolytes

what happens if more ions form?

Answer 11

dissolve in water mostly as molecules and a few ions
poor electrical conduction
as more ions form,they recombine

Question 12

nonelectrolytes

Answer 12

dissolve in water as molecules

Question 13

equivalent(Eq)

Answer 13

amount of each individual ion that is equal to 1 mole of positive/negative charge

Question 14

solubility

Answer 14

amount of solute that can dissolve in a given amount of solvent

Question 15

what is solubility expressed in?

Answer 15

grams of solute in 100 grams of solvent @ given temperature

Question 16

unsaturated solution

Answer 16

solute is readily dissolved in solvent (solution doesn’t have max solute)

Question 17

saturated solution

Answer 17

solution that has max solute it can dissolve

Question 18

what will happen to the solutes in a saturated solution?

Answer 18

solute recrystallizes and dissolves

Question 19

as temp goes up, what happens to the solubility of liquids?

Answer 19

increases

Question 20

when a saturated solution cools, what is the solution called?

Answer 20

super saturated solution

Question 21

as temp goes up, what happens to the solubility of gases?

Answer 21

solubility of gas decreases

Question 22

Henry’s law

Answer 22

solubility of gas in liquid is directly related to pressure of gas above liquid

Question 23

soluble salts

Answer 23

ionic compounds that dissolve in wate

Question 24

rules of soluble salts:

Answer 24

contains Li+,Na+,K+,NH4-,NO3-.C2H3O2-
Cl-,Br-,I- UNLESS combined w/ Ag+, Pb+,Hg2(2+)
SO4(2-) UNLESS contains Ba2+,Pb2+,Ca2+,Sr2+,CO3(2-),S2-, PO4(3-), OH-
