Was spraying oven cleaner on a somewhat rusted grill and my son, who is taking AP chemistry, asked about the green color that appeared. googled sodium hydroxide + iron oxide and got this
FeO + 4NaOH = Na₄FeO₃+ 2H₂O
but can't find any info on Na₄FeO₃ - would this have a green tint, and is there an explanation?
