Solubility Rules

Question 1

Always soluble, no exceptions?

Answer 1

NH4+, all alkali metal ionic compounds, acetates, nitrates, chlorate/chlorites

Question 2

Soluble if not for the troublemakers?

Answer 2

Binary chlorides, bromides, iodides

Question 2

The three main troublemakers?

Answer 2

Ag, Hg(i), Pb

Question 3

The rest of them?

Answer 3

Mg, Ca, Sr, Ba

Question 4

Soluble if not for any of the irregulars?

Answer 4

Sulfites

Question 5

Insoluble except for always?

Answer 5

Hydroxides, Carbonates

Question 6

Sulfides?

Answer 6

insoluble except for Mg, Ca, Sr, Ba, 1st rule

Question 7

To remember when asked for types of acid reactions?

Answer 7

Global warming turns freshwater acidic, acid + metal –> salt + hydrogen

Question 8

Category of bases that are immediately recognizable?

Answer 8

metal oxides (Arrhenius base)

Question 9

amphoteric?

Answer 9

either acid or base, based on Brønsted definition (are able to both donate or accept a proton)

Question 10

Conjugates?

Answer 10

Brønsted definition only, acid = add a proton, up a charge
base = remove a proton, down a charge

Question 11

What kinds of hydrogen cannot be removed/involved in any reaction?

Answer 11

Hydrogens bonded to a C

Question 12

Net ionic equation for any neutralization reaction?

Answer 12

H+OH–>H2O

Question 13

Oxidation number of hydrogen?

Answer 13

+1, but -1 when bonded to metals in binary compounds

Question 14

Types of displacement reactions

Answer 14

Hydrogen, metal, halogen (named after B element)

Question 15

Disproportionation?

Answer 15

an element is both oxidized and reduced
ex. 2H2O2 –> 2H2O + O2
