Question

what is the net ionic equation of the reaction of FeCl2 with NaOh

Answer 1

For the chemical equation, simply replace the name of each compound with its chemical formula:

NaOH + FeCl2 --> Fe(OH)2 + NaCl

Balance if necessary.

For the net ionic equation, determine which compounds are soluble and insoluble. If soluble, split it up into its component ions:

Na(+) + OH(-) + Fe(2+) + Cl(2-) -----> Fe(OH)2 + Na(+) + Cl(-)

Since Na(+) and Cl(-) are present on both sides of the equation you can ignore them. Your net ionic equation, then, is:

Fe(2+) + OH(-) -----> Fe(OH)2.
