Ionization & Dissociation Warm Up Review

Which is the correct net ionic equation for the reaction of AgNO₃ and CaCl₂?

• Ca²⁺(aq) +  2Cl^1- (aq) → CaCl(s)
• Ag⁺(aq)  +  Cl^1- (aq) → AgCl(s)
• Ag +  Cl  →  AgCl
• Ag⁺  +  Ca²⁺   →Ag₂Ca (s)

What are the spectator ions in this reaction?
CuCl₂(aq) + NaOH(aq) → Cu(OH)₂(s) + NaCl(aq)
 

• Cu²⁺ and OH^1-
• Na²⁺ and Cl^2-
• Na¹⁺ and Cl^1-
• Na¹⁺ and OH^1-

What are the spectator ions in the reaction of sodium chloride with silver nitrate?

• silver and nitrate
• sodium and chloride
• sodium and nitrate
• silver and chloride

what is the net ionic equation for the reaction 
2NaOH(aq) + CuCl₂(aq) → 2NaCl(aq) + Cu(OH)₂(s)

• 2OH^–(aq) + Cu²⁺(aq)  →  Cu(OH)₂(s)
• 2OH^–(aq) + Na⁺(aq) → NaOH(s)
• 2Cl^–(aq) + Cu²⁺(aq) → CuCl₂(s)
• Cl^–(aq) + Na⁺(aq) → NaCl(s)

The separation of ions that occurs when an ionic compound dissolves is

• ionization

• dissociation

• electronegativity

• spectation

They process in which ions are formed from molecules when they are dissolved in solution.

• dissociation

• ionization

• spetation

• electronegativity

What determines whether a polar molecule will be ionized in a polar solvent?

• the attraction of the polar solvent is stronger than the covalent bond in the solute

• the attraction of the polar solvent is weaker than the covalent bond in the solute

• only non-polar molecules are ionized

• molecular compounds are never ionized

If an electrical current can run through a solution, it is said to contain

• magic

• spectator ions

• electricity

• electrolytes

Ba(OH)₂

• strong electrolyte

• weak electrolyte

• non - electrolyte

CO₂

• strong electrolyte

• weak electrolyte

• non electrolyte
