Electrolytes and Nonelectrolytes Tested Substance Observed Conductivity (Indiente S, WON) Formulas of Speeles (molecules, tons or both) Underline ions in low concentrations are homogenous binations of phy Sis, gases can disse is a homogeneo ent, you will mak a semipermeable Ong electrolyte, Distilled water N Ethanol, C2H5OH Ethanol solution, CHSOH(aq) "Glacial"HC2H30. (17 M) cedure RT 1. Super ot scratched kap water and towel. Fill the water, rin gently to boil and tube e wate 0.10 M HC2H5O2 Sugar, C12H22011 (3) sho C12H22011 (aq) NaCl (s) 0.10 M NaCl 0.10 M HCI 0.10 M NaOH 0.10 M NH4OH 10-4

not understanding how to do these

Answer 1

Solution:

The electrical conductivity of the solution is due to the presence of ions. Thus, the substance which forms ions in aqueous solution conduct electricity.

Tested substance	Observed conductivity	Formula of species
Distilled water	N	H2O
Ethanol (C2H5OH)	N	C2H5OH
Ethanol solution	Y	C2H5O-(aq), H+ (aq)
Glacial CH3COOH (17M)	N	CH3COOH
0.1 M CH3COOH	Y	CH3COO- (aq), H+ (aq)
Sugar ( C12H22O11) (s)	N	C12H22O11
C12H22O11 (aq)	N	C12H22O11
NaCl (s)	N	NaCl
0.1 M NaCl (aq)	Y	Na+(aq), Cl-(aq)
0.1 M HCl	Y	H+ (aq), Cl-(aq)
0.1 M NaOH	Y	Na+ (aq), OH- (aq)
0.1 M NH4Cl	Y	NH4+ (aq), Cl-(aq)
