Test 3

Question 1

electrolyte

Answer 1

solution that conducts electricity due to the presence of ions

Question 2

ionic compounds(salts) form

Answer 2

ions when dissolved

Question 3

molecules(covalent compounds)

Answer 3

do not form ions in solution

Question 4

acids form

Answer 4

ions and are electrolytes

Question 5

solubility

Answer 5

the maximum amount of solute in grams that can be dissolved in 100g of solvent at STP

Question 6

solubility units

Answer 6

g/100g, M, g/mL

Question 7

m1v1=

Answer 7

m2v2

Question 8

molar solubility

Answer 8

maximum amount of solute that can be dissolved in 100g of solvent in molarity

Question 9

ksp(solubility product constant)

Answer 9

equilibrium constant in terms of the product of the ion concentrations at saturation raised to the power of its coefficients

Question 10

ksp requirements

Answer 10

-temperature dependent
-no units
-can determine from molar solubility

Question 11

TIP(trial ion product/trial ksp/reaction quotient)

Answer 11

value where ion concentrations are plugged into the equilibrium expression to determine if a precipitate will form

Question 12

a precipitate will form

Answer 12

TIP>Ksp

Question 13

no precipitate will form

Answer 13

TIP<Ksp

Question 14

the solution is saturated

Answer 14

TIP = Ksp

Question 15

common ion effect

Answer 15

if a solvent contains an ion that is in an ionic compound, the solubility for that compound decreases
