Recall that electrolytes are classified as:
• Strong electrolytes: dissociate completely in water; include soluble ionic salts, strong acids, and bases
a. Ionic salts: those that follow the rules of being soluble in solubility rules
b. Strong acids: HCl, HBr, HI, HNO3, H2SO4, HClO4, HClO3
c. Strong bases: Group 1A and 2A (Ca and lower) metals paired with OH–, H–, O2–, or NH2–
Which of the following statements is true?
A. All soluble ionic compounds are weak electrolytes.
B. Weak electrolytes dissociate completely in water.
C. Aqueous solution of sucrose is a strong electrolyte.
D. Electrolyte solutions conduct heat.
E. NH3 is a weak electrolyte.
