pH + pOH
What is the difference between pH and pOH?
pH measures the concentration of hydrgen ions in a solution.
pOH measures the concentration of hydroxide ions in a solution.
True or False: an acid in a reaction forms a conjugate acid
False
Given the reaction:
A2 + 3 B + 2 C --> AB3C2
What would be the initial concentration of AB3C2?
0
If a substance has a low pOH, what does that tell us?
The substance is basic
When a base forms it's conjugate acid, what happens to the hydrogen ion count?
Given the reaction:
A2 + 3 B + 2 C --> AB3C2
What would be the change expression of B?
-3x
A chemist measures the pH and pOH of two substances to determine which one is the most acidic. Substance A was calculated to have a pH of 1.67, while substance B was calculated to have a pOH of 13.49. Which one is the most acidic?
Substance B
What would be the conjugate base of HNO3?
NO3-
Given the reaction:
A2 + 3 B + 2 C --> A2B3C2
What would be the equilibrium constant equation?
[A2B3C2] / [A2][B]3[C]2
What is the formula for pH?
pH = -log[H3O+]
What would be the conjugate acid of H2O?
H3O+
Consider the reaction below. The reaction begins with only reactants and the [X] is initially 0.500 M and the [Y] is initially 0.600 M. At equilibrium, the [X2Y] is 0.084 M. What is the value of Kc for this reaction?
2 X (g) + Y (g) → X2Y (g)
1.49
Calculate the pH of 0.0854 M ClO3- acid solution.

What would be the conjugate base H2SO4?
HSO4-
In the reaction:
A2 + B2 --> 2 AB
If: [AB] is x, E of [A2] is 0.200 and [B2] is 0.300, Kc is 3.4 x 10-14
What is x?
4.52 x 10-8
