B - Stoichiometry and Reactions in Aqueous Solutions

Question 1

amphoteric

Answer 1

can react with either acid or base

Question 2

steps to get mass of substance B from mass of substance A

Answer 2

get mols of substance a, multiply by mole ration (wanted over given)

now you have mols of b, get mass

Question 3

polyatomic ions, “ate” series, number of oxygens, charges, and exceptions

Answer 3

three oxygens, -1

exceptions:
CO3 2-
SO4 2-
PO4 3-

Question 4

polyatomic ions, “ite” series, number of oxygens, charges

Answer 4

1 less oxygen

charges same as “ate”

Question 5

polyatomic ions, “hypo-ite” series, number of oxygens, charges

Answer 5

2 less oxygens

same charges

Question 6

polyatomic ions, “per-ate” series, number of oxygens, charges

Answer 6

1 more oxygen

same charge
