Project #1377 - chemistry

Consider H2CO3 and NaOH. Answer the following questions about these two opposites.

  1. Name the acid and the base.
  2. Write out the dissociations of both the acid and the base in terms of the Arrrhenius definition.
  3. The acid is weak and the base is strong.  Discuss the number of dissociated ions versus the number of undissociated molecules present for both the weak acid and the strong base.
  4. Discuss the number of hydrogen ions present versus the number of hydroxide ions present for both the acidic solution and the basic solution.
  5. At equilibrium, the hydrogen ion concentration of  the acid is, [H+] = 1 x 10-5 M and the hydroxide ion concentration of the base is, [OH-] = 0.01M. Calculate the pH of the acidic solution and the basic solution. (Note: show your work for these calculations)
  6. Suppose the acid and the base are mixed together.  Write out the balanced chemical equation for this neutralizatiion reaction.
  7. In the above neutralization reaction, 100mL of a 2M acid solution is to be completely neutralized by a 1M base solution.  How many milliliters of the 1M basic solution will be required to completely neutralize the acid? (Note: show your work for these calculations)

 Be sure to explain all reasoning and show all steps leading up to the answers.
