Chap 4

Question 1

Precipitate

Answer 1

Insolibule solid caused by reaction

Question 2

ME, CIE, NE

Answer 2

ME: molecular equation, balanced, everything included, no ions

CIE: complete ionic equation, all ions

NE: spectator ions (strong electrolyte) aside, only precipitate present

Question 3

Strong acids

Answer 3

HNO3
H2SO4
HClO4
HCl
HBr
HI

Question 4

Strong bases

Answer 4

LiOH
NaOH
KOH
Ca(OH)2
Sr(OH)2
Ba(OH)2

Question 5

Arrhenius acid/base

Answer 5

Acid produces H+ when dissolved in water, base produces OH-

Question 6

Bronsted-Lowry acid/base

Answer 6

Acid donates a proton, base accepts a proton

Question 7

Polyprotic acid

Answer 7

acid releases more than 1 hydrogen

EX:
H2SO4 (become H2O SO2)
H3PO4
H2CO3 (become H2O and CO2)

Question 8

Oxidation

Answer 8

Increase in oxydation state, loss of electrons, charge more positive, reducting agent (species that reduces another, it itself is oxided)

Question 9

reduction

Answer 9

A
derease in oxydation state, gain of electrons, charge more negative, oxidizing agent (species that oxides another, it itself is reduced)

Question 10

Oxydation state

Answer 10

Elements are 0

monoatomic ion is the same as charge

fluorine is -1 in compounds

oxygen is usually -2 in compounds, exept peroxyde (o2 2-)

hydrogen is +1 in covalent compounds (withiout a metal) and -1 with metals binary compounds

Halogen is -1 in binary compounds, except whe with another halogen above it in the periodic table or with oxygen
