Equilibrium shift of the reaction and the pH of solution

1. The pressure on each of the following systems is decreased from 5 atm to 1 atm. Which way does the equilibrium shift in each of the following systems?

a.) 2CO2 (g) --> 2CO (g) + O2 (g)
b.) H2 (g) + I2 --> 2HI (g)

2. What is the pH of a solution if the H+ concentration is 7.2 X 10^-14 M?
Is this neutral, acidic, or basic?

3. Calculate pKa for the weak acid with a Ka value of 6.3 x 10^-3

4. Classify the salt NaF as acidic, basic, or neutral? Write a net ionic equation to explain your answer.
