Reaction 4 [copper (II) oxide → copper (II) sulfate] Sulfuric acid (H₂SO4) is corrosive. If you get it on your skin, wash it off immediately. 1. Using a dispensing pipette, add 1.5 mL of 6.0M sulfuric acid (H₂SO4) solution to the centrifuge tube. Be sure you are using sulfuric acid (H₂SO4). There are two acids used in this lab and if you confuse the two, the reaction will not work. 2. Stir gently with a glass stir rod. 3. Record your observations.

Reaction 4?
![➤ Reaction 4 [copper (II) oxide → copper (II) sulfate]
Sulfuric acid (H₂SO4) is corrosive. If you get it on your skin, wash it off immediately.
1. Using a dispensing pipette, add 1.5 mL of 6.0M sulfuric acid (H₂SO4) solution to the centrifuge
tube. Be sure you are using sulfuric acid (H₂SO4). There are two acids used in this lab and if you
confuse the two, the reaction will not work.
2.
3.
Stir gently with a glass stir rod.
Record your observations.
The blue colored solution results from the formation of copper(II) sulfate, which is soluble in
water. Water is also formed as a product in this reaction. Don't confuse the sulfate ion with the
sulfide ion when writing formulas.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd407bb69-65e0-4600-bfd9-f9e537a98b1a%2F66b46b6f-5cf2-4c58-8ed4-3c04f28ee0f1%2Fxgvo6oc_processed.jpeg&w=3840&q=75)
