How do you go from [H+] to pH?
pH = -log [H+]
Certain metals will react with acids to produce what?
hydrogen gas and a salt
What is the only organic that are electrolytes?

Is Ba(OH)2 an acid or a base
Base
If a solution has a pH of 7 then it is _?
Neutral
What is the hydrogen ion concentration of a solution with a pH of 3?
[H+] = 1.0 x 10-3 M
Why should an acid always be added slowly to water when constantly stirring?
It is a dangerous and exothermic process
Why do solutions of electrolytes conduct electricity?
They contain mobile ions
what are the two conjugate acid-base pairs
HCO3– + H3O+ → H2CO3 + H2O
H3O+ – H2O
H2CO3 – HCO3–
What do bases do for you in your gastric lining?
They help cancel out the acidity.
What happens to the concentration of H+ when the pH is lowered?
it is greater
Will the reaction below occur? Why?
2Al + 3H2SO4 → Al2(SO4)3 + 3H2
Yes, it will occur since Al is more reactive than H on Table J
True/False- electrolytes conduct electricity because they dissolve into freely mobile ions in water that can conduct change
True!
Are acids or bases H+ acceptors on the reactants side?
Bases
What does the pH scale run from?
0-14
A student diluted a solution of pH 4 to pH 6. Compare the [H3O+] of the new solution to that of the original solution. Which solution is more acidic and why?
[H+] = 10-4 = .0001 M
[H+] = 10-6 = .000001 M
.000001 x 100 = .0001
The original solution would be more acidic due to its low pH.
What must always be looked at when solving a titration problem?
mole ratio of H+ to OH-
What category of electrolyte is CH3CH2COOH?
Organic acid
