Homework Help: Chemistry

Posted by Esmeralda on Sunday, September 12, 2010 at 10:11pm.

I have a lab for chemistry that I have to turn in soon, and I have no idea what the major and minor species if any of each of the substances we tested. Can someone please help me answer which one is the major/minor species of each of the elements?
They are:

1. H2O(deionized)[NO CONDUCTIVITY, NO ELECTROLYTES]

2. H2O(tap)[MEDIUM CONDUCTIVITY, WEAK ELECTROLYTES]

3. NaCl(s)[NO CONDUCTIVITY, NO ELECTROLYTES]

4. NaCl(aq)[HIGH CONDUCTIVITY, STRONG ELECTROLYTES]

5. CaCO3(s) + H2O(l)[MEDIUM CONDUCTIVITY, WEAK ELECTROLYTES]

6. CH3CH2OH(L)[NO CONDUCTIVITY, NO ELECTROLYTES]

7. CH3CH2OH(AQ)[NO CONDUCTIVITY, NO ELECTROLYTES]

8. C12H22O11(AQ)[NO CONDUCTIVITY, NO ELECTROLYTES]

9. HC2H3O2 17M(L)[NO CONDUCTIVITY, NO ELECTROLYTES]

10. HC2H3O2(AQ)[MEDIUM CONDUCTIVITY, WEAK ELECTROLYTES]

11. HCL IN TOLUENE[NO CONDUCTIVITY, NO ELECTROLYTES]

12.HCL(AQ)[HIGH CONDUCTIVITY, STRONG ELECTROLYTE]

13. NaOH(AQ) [HIGH CONDUCTIVITY, STRONG ELECTROLYTE]

14. 1.0M NH3(AQ)[MEDIUM CONDUCTIVITY, WEAK ELECTROLYTE]

15. 15M NH3(AQ) [LOW CONDUCTIVITY, WEAK ELECTROLYTE]
