Acids and bases both react to form…
Salt and water through neutralization
pH level of Acids
pH < 7
pH level of bases
pH > 7
CH3OH are ____
NOT bases. They are alcohols (organic chemistry unit)
The presence of ___ are what makes acids (Table K)
H+ ions
The presence or ___ is what are makes a base (table L)
OH-
acids + bases =
Water and salt
How can titration be used to find an unknown concentration of an acid/base?
Titration is used to find the unknown concentration of an acid/base by slowly adding a base/acid of known concentration to the acid/base until it is neutralized.
Hydronium
H+ ions / acid / H3O+
Hydroxide
Base / OH-
In terms of ions, Increasing pH means…
Less H+ ions and more OH- ions (more basic).
In terms of ions, decreasing pH means…
More H+ ions and less OH- ions (more acidic).
Diprotic
Two hydrogens are released
Monoprotic
Single hydrogen
Electrolyte
When dissolved (aqueous) of liquid, releases ions and allows for electrical current
Arrhenius base
Produces hydroxide ions when dissolved in water
Amines are…
Bases
Arrhenius acid
Solution where hydrogen ion is the only positive ion
The more an acid/base ionizes…
The stronger the acid/base
If releases a lot of ions…
Very strong and are better conductors of electricity since more electrolytes
Since molarity = moles/liters then…
#ofmoles = molarity x liter
Higher molarity = …. (In terms of conductivity)
more conductive
Molarity = …
Concentration
Acids release …. when they dissolve
H+ ions
ALL salts are
Ionic (conduct electricity)
Ionic solids release…
Ions
Higher molarity = ….
more ions
Electrolytes
Split apart when dissolved in water into charged particles
Covalent bonds are NOT electrolytes because
They do not dissociate into ions and they do not conduct electricity
When an acid/base needs more volume to balance/neutralize the same number of moles of different acid/base, it must be….
Weaker than the other acid/base (stronger one) because you are using a larger amount to balance the stronger acid/base
Molarity tells you
How concentrated an acid/base is.
pH means
Potential of hydrogen
If concentration changes by 10…
pH changes by 1
If pH changes by 1…
Concentration changes by 10
1 × 10^-11 tells you… (about pH level)
That the pH is 11 since the exponent is negative 11.
