Acids
An acid that produces many hydrogen ions or hydronium ions when it is dissolved in water.
Strong Acid
Bases typically release these ions when they are dissolved in water.
Hydroxide (OH-)
This is a substance that changes color in the presence of an acid or a base.
Indicator
When acids and bases or equal strengths combine, they will completely ________.
Neutralize
When rain mixes with pollution in the air, primarily from cars and electrical power plants, it will produce this product
Acid rain
What gas product do acids create when they react with carbonates, like when vinegar was mixed with baking soda?
Carbon Dioxide (CO2)
Bases taste _______.
Bitter
(True or False) A very basic solution would have a pH of 8.
False. Very basic means it would be much higher than 8.
In neutralization reactions, acids and bases yield what two products?
Water and Salts
These are used as artificial flavorings in several foods, and typically have a fruity scent and flavor
Esters
Acids are found (above or below) 7 on the pH scale.
Below
The pH ranges of bases are
above 7 to 14
An indicator used in most titrations, that turns a very bright and pretty pink in the presence of a base
Phenolphthalein
This is the method by which a solution of known concentration is used to determine the unknown concentration of a second solution.
Titration
An organic salt that has a nonpolar chain of carbon atoms on one end and a sodium or potassium salt on the other.
soap
Name a strong acid we discussed in class.
Sulfuric acid, nitric acid, or hydrochloric acid.
Name a strong base we discussed in class - like the one that ate through the coca cola can.
Sodium hydroxide or calcium hydroxide.
Red litmus paper turns blue in the presence of an acid or a base?
A base
This is reached when the concentration of H+ ions equals the concentration of OH- ions.
Equivalence Point or endpoint
A mixture of chemicals that conducts an electric current is called what?
Electrolyte
What kind of tastes are associated with acids?
Sour
Name a weak base we discussed in class.
Ammonia or Aluminum hydroxide, soap or detergents.
This is another word for a base.
Alkaline
This is the most commonly used indicator in titration.
Phenolphtalein
solutions containing ions that react with additional acids or bases to minimize their effects on the pH.
