Acids
All acids dissociate in solution to release these ions.
What are H+ ions?
What are H3O+ ions?
Bases have a pH value between these numbers.
What are 7 and 14?
The name and formula of the acid formed when carbon dioxide reacts with water.
What is carbonic acid, H2CO3?
CO2 + H2O --> H2CO3
The name and formula of the acid found in seawater that dissolves oyster shells and makes forming new shells more difficult.
What is carbonic acid, H2CO3?
This changes color in the presence of an acid or a base.
What is an indicator?
The sum of the coefficients in the net ionic equation of this reaction:
3AgNO3 ( ) + Na3PO4 ( ) --> 3NaNO3 ( ) + Ag3PO4 ( )
What is 5?
3AgNO3(aq) + Na3PO4(aq) --> 3NaNO3(aq) + Ag3PO4(s)
3Ag+(aq) + PO43-(aq) --> Ag3PO4(s)
3 + 1 + 1 = 5
The difference between a strong acid and a weak acid.
What is strong acids completely dissociate, while weak acids barely dissociate?
HCl --> H+ + Cl-
CH3COOH <--> H+ + CH3COO-
Bases accept these from acids.
What are hydrogen ions, H+?
An acid and a base react to form these.
What are a salt and a water?
HCl + NaOH --> NaCl + H2O
This term is used to describe a salt, like calcium carbonate, that does not dissociate in water.
What is insoluble?
The term given to a salt that dissolves in water.
What is soluble?
What is aqueous?
The names of the three stong acids.
What are hydrochloric, nitric, and sulfuric?
HCl HNO3 H2SO4
Most bases dissociate in solution to release these ions.
What are hydroxide ions, OH-?
An equation that shows only the molecules or ions that are actively involved in the reaction or those that undergo a change.
What is a net ionic reaction?
The name and formula of the main component of oyster shells, coral, or chicken eggs.
What is calcium carbonate, CaCO3?
The term given to a reaction that is faster... more bubbles... more violent... more reactive.
What is vigorous?
The name and formula of the ion that is formed when H+ reacts with water.
What is the hydronium ion, H3O+?
This weak base has a very pungent odor and does not contain a hydroxide ion.
What is ammonia, NH3?
A metal reacts with an acid to produce this gas.
What is hydrogen gas?
Mg + 2HCl --> MgCl2 + H2
This ion removes carbonate ions (CO32-) from seawater, preventing oysters from using them to build new shells.
What are hydrogen ions, H+?
The term given to an acid that releases two hydrogen ions.
What is diprotic?
H2SO4 --> 2H+ + SO42-
Sulfuric acid dissociates into these three ions.
What are H+, HSO4-, and SO42-?
H2SO4 <--> H+ + HSO4-
HSO4- <--> H+ + SO42-
The name of the base in the following reaction:
CH3COOH + NaHCO3 --> Na+CH3COO- + H2CO3
What is sodium hydrogen carbonate (baking soda)?
NaHCO3
The net ionic equation of this reaction:
HCl (aq) + NaOH (aq) --> NaCl (aq) + H2O (l)
What is H+ (aq) + OH- (aq) --> H2O (l) ?
The two salts that dissolve in water to form calcium carbonate.
What are calcium chloride, CaCl2, and sodium carbonate, Na2CO3?
CaCl2 --> Ca2+ + 2Cl-
Na2CO3 --> 2Na+ + CO32-
Ca2+ + CO32- --> CaCO3 (s)
The pH of a solution with [H+] = 0.001
-log(.001) = 3
