Question

For Part 1, describe the changes in the colors of the well, if any, as you go from well 1 to well 9—that is, as you go from the well with the least copper(II) nitrate to the well with the most copper(II) nitrate. Which wells had the most distinct precipitate?
For Part 2, describe the changes in the colors of the well, if any, as you go from well 1 to well 9—that is, as you go from the well with the least iron(II) sulfate to the well with the most iron(II) sulfate. Which wells had the most distinct precipitate?

For Part 3, describe the changes in the colors of the well, if any, as you go from well 1 to well 9—that is, as you go from the well with the least iron(III) nitrate to the well with the most iron(III) nitrate. Which wells had the most distinct precipitate?

Answer 1

Answer:

Nitrate is a polyatomic ion with the molecular formula NO⁻₃

Explanation:

treat (a substance) with nitric acid (typically a concentrated mixture of nitric and sulfuric acids), especially so as to introduce nitro groups

a salt or ester of nitric acid, containing the anion NO3− or the group —NO3..

Answer 2

Answer:

Nitrate is a polyatomic ion with the molecular formula NO⁻₃ and a molecular mass of 62.0049 u. Organic compounds that contain the nitrate ester as a functional group are also called nitrates.
