Electrolyte/Nonelectrolyte

Friday, May 21, 2010, we read pages 19 to 29. We learned new terms like electrolyte and non
electrolyte. "conducts electricity" is an electrolyte and "do not
conduct electricity" is a non electrolyte. An example of a non
electrolyte is water (H2O). An example of an electrolyte is sodium
hydroxide (NaOH). Then, Ms. K showed us a demo that determine if a
compound is an electrolyte or non electrolyte. We looked at questions
on page 22. Questions 4, 9, 10 and 14 are identified as non
electrolytes. We added 2 questions #13. H2O and #14. NaCl. Electrolytes
are question #s 1,2,3,5,6,7,8,11,12,13,14.
*all organic compounds are NON electrolytes*
*strong acids are ALWAYS strong electrolytes*
*strong acids are considered to completely dissociate in water*
We also did the 'calculating the dissociation constant' on page 29.
After the booklet, Ms. K assigned us to do Acid -Base Equilibria
Worksheet 4 questions #1-4.
Have a nice long weekend!!!
