Question

8. Show the chemical equation for the reaction between acetic acid (HC H,O) and water. Is this a reversible reaction? If so, what type of value does K have for the reaction? Show the reaction between nitric acid and water. Is this a reversible reaction? If so, what type of value does K have for the reaction? 9. Sulfuric acid is a diprotic acid with the formula H,SO. Phosphoric acid is a triprotic acid with the formula H:PO4. Which will have a lower pH as aqueous solutions? A 1 M solution of H SO, or a IM solution of H:PO:? Explain with words and equations. Acids and bases react by "proton transfer". Describe what is meant by a proton when discussing acids and bases (Bronsted-Lowry). Describe how a hydrogen atom is different than a proton, is different than a hydronium ion. Show 11. the equation for the reaction of hydrochloric acid with sodium hydroxide. Show the equation for the reaction of sulfuric acid with sodium hydroxide. 12. Water is said to be amphoteric? What does this mean? Use words and equations. Provide formulas and structures for hydronium and hydroxide ions in your answer. Ammonia is also amphoteric; using structures and electron movements show how ammonia can form hydroxide when ammonia is mixed with water.

Explanation / Answer

8. acetic acid is a weak acid dissociated to a small extent in solution

CH3COOH + H2O <==> CH3COO- + H3O+

This is a reversible reaction with very low K

HNO3 is a strong acid, dissociated completely in solution

HNO3 + H2O ---> H3O+ + NO3-

This is an irreversible reaction. K is very high

9. H2SO4 is a strong acid which dissociated completely in solution

H2SO4 --> 2H+ + SO4^2-

so the pH is very low for the solution

H3PO4 is a weak acid and dissociates only to a small extent in solution

H3PO4 --> 2H+ + HPO4^2-

The third dissociation is extremely small and does not affect the pH of the solution

Of the two H2SO4 would have lowest pH value (highly acidic, high H+ concentration) than H3PO4
