Question

Write a balanced molecular and net ionic equation for:

Ca(OH)₂ (aq) + FeCl₃ (aq)
Options:
A. Ca(OH)₂ (aq) + FeCl₃ (aq) → CaCl₂ (aq) + 2Fe(OH)₃ (s)
B. CaCl₂ (aq) + 2Fe(OH)₃ (s) → Ca(OH)₂ (aq) + FeCl₃ (aq)
C. Ca(OH)₂ (aq) + FeCl₃ (aq) → CaCl₂ (aq) + Fe(OH)₃ (s)
D. CaCl₂ (aq) + Fe(OH)₃ (s) → Ca(OH)₂ (aq) + FeCl₃ (aq)

Answer 1

The balanced molecular and net ionic equations for the reaction between Ca(OH)2 (aq) and FeCl3 (aq) are Ca(OH)2 (aq) + 2FeCl3 (aq) -> CaCl2 (aq) + 2Fe(OH)3 (s) and 3OH- (aq) + Fe3+ (aq) -> Fe(OH)3 (s), respectively.

Step-by-step explanation:

The correct balanced molecular and net ionic equation for the reaction between Ca(OH)2 (aq) and FeCl3 (aq) is:

Ca(OH)2 (aq) + 2FeCl3 (aq) → CaCl2 (aq) + 2Fe(OH)3 (s)

This equation shows that when Ca(OH)2 reacts with FeCl3, it forms CaCl2 and Fe(OH)3 which is a precipitate. The net ionic equation can be written as:

3OH- (aq) + Fe3+ (aq) → Fe(OH)3 (s)
