Equilibrium Shift
If you increase pressure, which way will this reaction shift in its equilibrium?
N2(g) + 3 H2(g) <--> 2 NH3(g)
To the right.
How do acids taste?
Sour.
How do bases taste?
Bitter.
If you are given
[OH-]= 5.25 x 10-6 M, find [H+]
0.00000000002M or 2.0E-9
True or False: A soluble salt solution is an electrolyte.
What is True?
If you remove NH3, which way does this reaction shift in its equilibrium?
N2(g) + 3 H2(g) <--->2 NH3(g)
To the right.
What do acids react with to make water?
Bases.
What do bases react with to make water?
Acids.
If [H3O+] = 1.8 x 10-3 M, find the [OH-]
5.55E-12 M
True or False: Acid strength is referring to its concentration.
What is False?
If you add more N2, which way will this reaction shift in its equilibrium?
N2(g) + 3 H2(g) <--->2 NH3(g)
To the right.
If you add acid to blue litmus paper, what color does it make?
Red/pink.
What color do bases turn red litmus paper?
Blue.
If pH=4.87, find [H3O+]
0.00001349 M
This is the chemical reaction that titrations utilize.
What is neutralization?
Without changing the amount of H2 and N2 in the flask, how could you shift the reaction equilibrium to make more NH3?
N2(g) + 3 H2(g) <---> 2 NH3(g) + heat
Ice (lower temp), Take out some NH3, Increase Pressure.
Where do acids rank on the pH scale?
Below 7
On the pH scale, where do bases rank?
Above 7
If [OH-] = 5.6x10-11 M, find the pH.
pH is 3.75
An electrical circuit containing a light bulb dimly lit likely has this kind of electrolyte involved.
What is a weak electrolyte?
OR what is a weak acid/base?
If you add a catalyst, which way would this reaction shift in its equilibrium?
N2(g) + 3 H2(g) <---> 2 NH3(g)
It has no shift / no effect.
What do acids react with to make hydrogen gas?
What are (active) metals?
What do bases NOT readily react with?
Metals.
The pH of a solution of HBr is found to be 2.45. find the concentration of [H+] in solution and the pOH.
