Ok there’s this question on my chemistry review that I can’t figure out. It states:
A sample of well water is known to contain a high concentration of iron. what solution could you use to test the water to get a positive precipitate test for the dissolved iron? I don’t understand it because how can the iron dissolve in water?
I tried writing that NaOH would be able to create a precipate with iron because FeOH would be insoluble together but Na is more reactive than Fe so that wouldn’t displace.
Can someone explain the answer to me (by the way the teacher wrote that there are many solutions and NaOH is one of them)
