The organic base 4-toluidine is prepared by reduction of 4-nitrotoluene
(which is not basic). Both solids dissolve readily in dichloromethane
(density = 1.316 g/mL), but poorly in water.
A student trying to prepare 4-toluidine found that the reaction had not
gone to completion. She then used solvent extraction to separate the
4-toluidine from unreacted 4-nitrotoluene as illustrated.
Complete the balanced ionic equation for the reaction in step 2.
