Worksheet # 2 Strength of Acids and Bases
1.- Name the 3 types of compounds that tend to form electrolytes.
2.- A solution of HCl in water conducts electricity but HCl in hexane does not conduct
electricity. Explain.
3.- A solution of CH3OH in water does not conduct electricity, and a solution of NaOH in
water does. Explain.
4.- Which of the following compounds are electrolytes when dissolved in water? Justify
your answer.
a)HCl g)NaHCO3
b)CO2 h)AgNO3
c)CaCl2 i)HCOOH
d)C12H22O11 j)RbOH
e)C3H7OH k)K2CrO4
f)CCl4 l)NH3
5.- Identify the following as strong electrolyte, weak electrolyte or nonelectrolyte:
a)HC2H3O2 d)Al(OH)3
b)HNO3 e)C12H22O11
c)Ca(OH)2 f)HCl
6.- When ionic compounds dissolve to produce ions the process is typically called
dissociation. Example: Na2SO4  2 Na+1 + SO4 2-
When molecular compounds dissolve in water (like acids) to produce ions the process is
typically called ionization. Example: H2SO4  H+ + HSO4-
a)Write a chemical equation for the dissociation of MgCl2
b)Write a chemical equation for the ionization of HNO3
c) Write the chemical equation for the dissociation of Al(OH)3
