Question
Classify the solutes in the following equations as a weak electrolyte, a strong electrolyte, or a nonelectrolyte
in water.
a. XY2(s)-----> X2+ (aq) + 2Y-(aq)
b. HX(g) ------> H+(aq) + X-(aq)
c. XYZ(s)------> XYZ(aq)
d. YOH(s) ------> Y+ a(q) + OH- (aq)
write an equation for their solution in water: in these equation can you please help me to identified which one is a strong, weak or non electrolyte? and I need specified with one is a (s), (aq), (I) . For example glucose i am not sure if a a substance..
HCl(aq) + H2O(I) ---------->Cl-(aq) + H3O+ (aq)
NH4OH(aq) -------------------> NH4+(aq) +OH-(aq)
<----------------->
C6H12O6 + H2O ------------>C6H12O6 (aq)
Explanation / Answer
solutes are classified in the following equations as a weak electrolyte, a strong electrolyte, or a nonelectrolyte
in water.
a. XY2(s)-----> X2+ (aq) + 2Y-(aq) (complete dissociation - strong electrolyte)
b. HX(g) ------> H+(aq) + X-(aq) (complete dissociation - strong electrolyte)
c. XYZ(s)------> XYZ(aq) (No dissociation - Non - electrolyte)
d. YOH(s) ------> Y+ (aq) + OH- (aq) (Partial dissociation - weak electrolyte)
Strong electrolytes conduct current very efficiently completely ionized or dissociate when dissolved in water.
Weak electrolytes conduct only a small current slightly ionized in solution.
Nonelectrolytes conduct no current, no ions present in solution.
HCl(aq) + H2O(I) ---------->Cl-(aq) + H3O+ (aq) (complete dissociation - strong electrolyte)
NH4OH(aq) -------------------> NH4+(aq) +OH-(aq) (Partial dissociation - weak electrolyte)
C6H12O6 (s) + H2O (l) ------------>C6H12O6 (aq) (No dissociation - Non - electrolyte)
