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.

Question
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.
