Question 1

Solution

Answer 1

Homogeneous mixture composed of a solute dissolved in a solvent

Question 2

Solute

Answer 2

substance of lower concentration that is dissolved in solution

Question 3

Solvent

Answer 3

substance of higher concentration that dissolves the solute in solution

Question 4

mass percent

Answer 4

mass solute/mass solute + solvent x 100%

Question 5

molarity of solution

Answer 5

moles solute/# liters solution

Question 6

New molarity

Answer 6

M1V1=M2V2

Question 7

3 properties of acid

Answer 7

solutions with high concentration of hydronium[H3O+/H+] ions
ph 0-7
corrosive
reacts with metal
good electrolytes and conduct electricity well

Question 8

3 properties of bases

Answer 8

solutions with high concentration of hydroxide [OH-] ions
pH range 7-14
caustic
don’t reeact well w metals
only strong bases are good electrolyte

Question 9

what is strong acid

Answer 9

100% dissociation into [H+] hydornium ions
conducts electricity
strong electrolyte

Question 10

weak acid

Answer 10

partial dissociation into [H+] ions
weak electrolyte

Question 11

equation strong acid

Answer 11

HX –>100% H+ + x-

Question 12

equation for weak acid

Answer 12

HZ –> <— H+ + z-

Question 13

whats difference between strong base and weak base

Answer 13

strong base is 100% dissociation into [OH-] ions
weak base is partial

Question 14

what is pH? Formula

Answer 14

pH=concentration of
pH = -log[H+]

Question 15

What is [H+], how to find

Answer 15

Inverselog(-pH)

Question 16

What is [OH-] how to find

Answer 16

inverselog(-p0H)
pH+p0H=14

Question 17

Acid solution: pH range, [H+] high low, [OH-] high low

Answer 17

0-7, High, Low

Question 18

Base solution: pH range, [H+] high low, [OH-] high low

Answer 18

7-14, low, High

Question 19

Neutral solution: pH range, [H+] high low, [OH-] high low

Answer 19

7, [H+=OH-]
