Acids
Acids change litmus paper to this colour.
What is red?
Bases turn litmus paper this color...
What is blue?
A sample of pure water will autoionize, creating these two ions in solution?
What are hydronium and hydroxide?
This occurs when an acid and base are mixed together
What is a neutralization?
The name is hydrochloric acid.
What is HCl?
Physical properties of acids include: conducts electrical current and usually has a __________ taste.
What is sour?
Physical properties of bases include: conducts electrical current and has a __________ taste.
What is bitter?
T or F
A strong acid or base must have a concentration of at least 1.0 M.
What is false?
This is what tells you the pH of a solution during a titration experiment.
What is an indicator?
The formula is KOH.
What is potassium hydroxide?
Acids increase the number of positively charged ______ ions when dissolved in water.
What is hydrogen?
Bases will accept this specific elemental ion.
What is a hydrogen?
As the concentration of hydronium ions increases, this is what happens to the pH.
What is decreases?
A strong acid or base with a concentration greater than this will have a pH outside of the normal 0-14 range.
What is 1.0 M?
The formula is Fe(OH)3.
What is iron (III) hydroxide?
According to the Bronsted-Lowry model, acids are defined as these.
What are proton donors?
Based on this specific definition, the base will ionize and produce a hydroxide ion.
What is an Arrhenius base?
T or F:
In an acidic, aqueous solution, there will be zero hydroxide ions?
What is false?
An Arrhenius acid and base will produce this as a product.
What is water? or What is a salt?
The name is sulfurous acid.
What is H2SO3?
This is the pH range of an acid.
What is 0 - 7?
This is the pH range of a base.
What is 7 - 14?
An acid is very concentrated, but only has a pH of about 5. It must be this type of acid.
What is a weak acid?
(because only a small percentage of its molecules are dissociating, the pH never gets very low)
A solution with a pH of 2 is this this many times more acidic than a solution with a pH of 5.
What is 1000?
(each pH unit represents a 10x change in concentration!)
The formula is H3PO4.
What is phosphoric acid?
