pH and pOH
The pH range goes from __ to __
what is 1 to 14
HCl is a
a. weak base
b. strong acid
c. weak acid
d. strong base
b. strong acid
is defined as a substance that releases H+ or H3O+ ions (Hydronium ions) in an aqueous solution
what is An Arrhenius Acid
has a bitter taste
what is a base
If the HCl concentration of a solution is 1.30 x 10-4, what is the pH of the solution
3.886
Solve: -log(1.30 x 10-4)
Which of the following is considered in a strong base.
H2O, NH3, NaOH, or CH3NH2
NaOH
is defined as any species that can donate a proton (H+ ion) to another species
what is a Brönsted-Lowry acid
these substances have a sour taste and react with metal to release H2 gas
what is an acid
If the NaOH concentration of a solution is 2.8 x 10-6, what is the pH of the solution?
8.45
Solve: -log(2.8 x 10-6) = 5.55
14 - 5.55 = 8.45
which of these is considered a strong acid?
HNO3, HF, H2S, or HNO2
HNO3
a substance that, when dissolved in an aqueous solution, increases the concentration of hydroxide, or OH-, ions in the solution
what is an arrhenius base
Has a pOH greater than 7
what is an acid
If the hydroxide ion (OH-) concentration of a solution is 4.7 x 10-10M, what is the pH of the solution?
4.7
Solve: -log(4.7 x 10-10) = 9.3
14 - 9.3 = 4.7
Identify a base in the following equation. CH3COOH + NaOH -> Na+ + CH3COOH- + H2O
What is NaOH
Define a Brönsted-Lowry base
any species that can accept a proton (H+ ion) from another species; a proton acceptor
turns litmus paper blue
what is a base
If the hydrogen ion concentration of a solution is 3.6 x 10-9, what is the pOH of the solution
5.6
Solve: -log(3.6 x 10-9) = 8.4
14 - 8.4 = 5.6
identify the acids in this equation.
H2O + NH3 -> NH4+ + OH-
what is H2O and NH4+
In the following reaction which is the Bronsted-Lowry acid? NH3 + H2O → NH4+ + OH-
H2O
Strong acids turn litmus paper what color
what is red
