  1. Exam Review- Acids & Bases

  2. List 6 properties of acids. • List 6 properties of bases.

  3. Sour taste React with bases to produce salt & H2O (neutralization or DR) Turn blue litmus red Conduct electricity React with metals to produce H2 gas Must contain Hydrogen, H+ ions in formula Ex: H2SO4,HCl, HNO3 Bitter taste React with acids to produce salt & H2O Turn red litmus blue Conduct electricity Slippery Must contain hydroxide (OH-) ions or produce OH-in solution. EX: NaOH, Ba(OH)2, Mg(OH)2 AcidsBases

  4. What is the equilibrium equation for water Kw? • Write the equation for determining pH?

  5. Calculate the pH of the following solutions: 1.0 M KOH 2.4 x 10-5M HNO3 0.050 M HNO3

  6. Use your text Section 19.1 to answer the following: (that is if you need to use your text) • Write a balanced equation for the reaction between sulfuric acid and calcium metal • Write a balanced equation for the reaction between sodium bicarbonate and hydrochloric acid.

  7. If the [OH-] equals 1 x 10-10 at 298 K for a given solution, the [H+] of the solution equals _________________. • And the pH of the solution is ________.

  8. When the pH of a solution is 8, what is the OH- ion concentration in moles per liter?

  9. What is the H+ ion concentration of an aqueous solution that has a pH of 11? • What is the OH- concentration?

  10. Rank the pH scale from lowest to highest. • What represents the basic range? • What represents the acid range?

  11. An aqueous solution that has a hydrogen ion concentration of 1.0 x 10-8 mole per liter has a pH of _______________. • What is the pOH?
