Equilibrium and Acid-Base Reactions

1. The hydration reaction , Na2HPO4 + 2H2O -> Na2HPO4 x 2H2O has a Kp = 6000 at 300K

If excess dry, anhydrous Na2HPO4 is added to a 3L container holding 25mmHg of water vapor, what will be the pressure of water after it equilibrates with the sodium phosphate?

2. What is the pH if 2g of NaC2H3O2 and 1g of HC2H3O2 are mixed in 1 liter of solution. The Ka for acetic acid is 1.8 x 10^ -5.

Solution Summary

The solution examines equilibrium and acid-base reactions.
