Unit 10 Test Flashcards
What’s an acid
Something that produces hydrogen ions when dropped in H2O
What’s a base
Produces hydroxide ions when dropped in H2O
Whats an hydroxide ion
a negative ion produced when a base is placed in H2O
Whats a hydronium ion
a positive ion thats produced when acide is placed in H2O
Neutral solution
pH=7
pH
negative log of hydrogen ion concentraiton
Acid base indicator
weak acid or base that exhibits a color change
Amphoteric
H2O can be an acid or a base
Strong acid
dissociated completely and produces hydronium ion
Write acid and base thingy
1.0x10^-7
Acid -6, -5, -4
Base -8, -9, -10
What are these examples?
HCl
H2SO4
H3PO4
monoprotic
diprotic
triprotic
Draw the self-ionization of water
What are the products of the self-ionization of water?
H3O+ and OH-
Properties of acids
turns red, sour, less than 7 pH
properties of bases
turns blue, bitter, more than 7
The bigger the Ka value, the _______ the acid.
stronger
Which of these is a stronger acid?
4.8x10^-12
6.9x10^-5
6.9x10^-5
Arrhenius
is it creating [H+]=acid or [OH-]=base
Bronsteud Lowyrey
Acid is a proton donor and base is proton accepter
Airplane
Lewis
electrons? Lewis base donates lone pair of electrons
Lewis acid will accept the lone pair of electrons
Draw the lewis dot structure for NH3 and H2O
Describe Titration using words titrant analyte indicator equivalence point and H+ and OH-
A process where you add a known amount of a solution or titrant which is of known concentration in order to determine the concentration of a different solution known as an analyte. Drop by drop the indicator is added to the solution until it changes color. The change in color indicates that it has reached its equivalence/endpoint. The point of this process is to get the amount of H+ and OH- to equal amounts so that you can determine the concentration of the unknown substance.
