In neutral solutions, the concentration of H3O+ and OH- are 1x10 to the power of __
pH of acids are
less than 7
indicator
(chemistry) a substance that changes color to indicate the presence of some ion or substance
blue litmus paper
stays blue in bases
Bronsted-Lowry base
susbtance that accepts a proton
standard solution
the solution that contains the precisely known concentration of a solute
ammonia
a pungent gas compounded of nitrogen and hydrogen (NH3)
acids that contain 2 ionizable hydrogen (protons)
diprotic acids
they have a high pH; taste bitter
bases
H3C6H5O7
citric acid; making soft drinks, used as a preservative
Arrhenius base
Substance that produces hydroxide ions as the only negative ions when dissolved in water.
matter
material that makes up objects. Cannot be created or destroyed.
Amphi Protic
What is water in acids and bases?
acetic acid
a colorless pungent liquid widely used in manufacturing plastics and pharmaceuticals.
dilution is exothermic (add water, gets hot)
acids and bases
What are weak bases?
Weak bases ionize only slightly
acid
a compound that tastes sour and reacts with some metals
Yellow
The colour of Universal Indicator in a weak acid.
Arrhenius acid
compound that forms hydrogen ions (H+) in solution
Hydronium Ion
What is another term that describes a hydrogen ion?
weak acid
an acid that is only slightly ionized in aqueous solution
weak acids
an acid that ionizes only partially in dilute aqueous solution
What is the pH if the H+ concentration is: 1.0 X 10^-7
7
conjugate acid
the particle formed when a base gains a hydrogen ion
OH- ion
a hydroxide ion composed of an oxygen atom and a negative hydrogen ion
bronsted base
a molecule or ion that is a proton acceptor
acid-base indication
is a substance that turns one color in an acid solution and another color in a basic solution
most common is litmus paper
-acid: litmus paper from blue to red
-base: litmus paper from red to blue
What are polyprotic acids?
acids with more than one ionizable hydrogen (H3PO4); hydrogens leave one at a time; for the removal of each successive hydrogen, the ionizable constant is smaller
Arrhenius base is one that...
produces an OH- ion when it dissociates
What does it mean when they say Concentrated solution (refer to Particles)
Concentrated solution means that there are a lot of particles dissolved within the solution.
How do you determine the pH for weak acids?
pH=½pKa - ½log[HA]
So if you add more acid, the pH decreases. Bases substitute in pOH, pKb, and A⁻.
The equation assumes that the weak acid concentration is greater than the Ka and that the pKa is between 2 and 12.
