  • turn blue litmus paper red.

(319)

Term
indicator
Definition
a substance that turns one color in the presence of acids and another color in the presence of bases (320)
Term
General properties of bases:
Definition
  • taste bitter
  • are slippery to the touch when dissolved in water
  • turn red litmus paper blue

(320)

Term
Chemical definition of acid:
Definition
A molecule that donates H+ ions (322)
Term
Chemical definition of base:
Definition
A molecule that accepts H+ ions (322)
Term
Proton donor
Definition
Another name for an acid: Acids donate H+ ions, which are protons. (322)
Term
Proton acceptor
Definition
Another name for a base: Bases accept H+ ions, which are protons. (322)
Term
hydronium ion
Definition
a water molecule with an extra hydrogen ion attached to it: H3O+ (323)
Term
amphiprotic compounds
Definition
Compounds that can act as either an acid or a base, depending on the situation (324)
Term
When ionic compounds dissolve, they:
Definition
split into their constituent ions. (325)
Term
polyprotic acid
Definition
An acid that can donate more than one H+ ion. (329)
Term
Triprotic acid
Definition
An acid that can donate three H+ ions. (329)
Term
Diprotic acid
Definition
An acid that can donate two H+ ions. (329)
Term

You can use the following general guideline to determine the products of an acid/base reaction:

ACID + BASE --> ________ + ___________

Definition

ACID + BASE -->    SALT    +   WATER  

 (330)

Term
Neutralization reaction
Definition
A reaction between an acid and a base that neutralizes both, typically forming salt and water. (330)
Term
Molarity (M)
Definition
A concentration unit that tells how many moles of a substance are in a liter of solution. It is determined by taking the number of moles of a substance and dividing by the number of liters of solution. (334)
Term
Dilution
Definition
Adding water to a solution in order to decrease the concentration (337)
Term
Dilution equation:
Definition

M1V1 = M2V2

(337)

Term
When nummber of moles is divided by volume (in liters), you get__________.
Definition
Molarity (340)
Term
When molarity is multiplied by volume (in liters), you get ___________________.
Definition
Number of moles (340)
Term
Titration
Definition
The process of slowly reacting a base of unknown concentration with an acid of known concentration (or vice versa) until just enough acid has been added to react with all of the ase. This process determines the concentration of the unknown base (or acid). (341)
Term
Endpoint of the titration
Definition
The point in a titration where the acid and base have completely reacted with one another. It is usually accompanied by an indicator's change in color. (342)
Term
Buret
Definition
Piece of laboratory glassware used (primarily for titration) to deliver solution in precisely-measured, variable volumes. Used to deliver one reactant until the precise end point of the reaction is reached. (345)
