Physical & Chemical Changes Virtual Lab Flashcards

Vocabulary flashcards summarizing the physical and chemical observations recorded before and after mixing solutions in Virtual Lab reactions 1 through 10.

Reaction 1: Sodium Hydroxide + Nickel (II) Nitrate

Clear liquid Sodium Hydroxide mixes with light blue/cyan liquid Nickel (II) Nitrate to become light green on top and dark green on the bottom with no tube heating.

Reaction 2: Potassium Iodide + Lead (II) Nitrate

Clear liquid Potassium Iodide and clear liquid Lead (II) Nitrate mix to form yellow strands of color with remaining clear liquid, and the tube becomes heated.

Reaction 3: Sodium Carbonate + Calcium Chloride

Clear liquid Sodium Carbonate and clear liquid Calcium Chloride mix to create a white color line going from the top to half of the tube, without tube heating.

Reaction 4: Potassium Acetate + Silver Nitrate

Clear liquid Potassium Acetate and clear liquid Silver Nitrate result in no chemical reaction, no color change, and no tube heating.

Reaction 5: Sodium Carbonate + Nitric Acid

Clear liquid Sodium Carbonate and clear liquid Nitric Acid mix to produce bubbling while remaining clear in color, and the tube feels heated.

Reaction 6: Sodium Hydroxide + Nitric Acid

Clear liquid Sodium Hydroxide and clear liquid Nitric Acid result in no color change at all, but the tube feels heated.

Reaction 7: Sodium Acetate + Sulfuric Acid

Clear liquid Sodium Acetate and clear liquid Sulfuric Acid result in no color change at all, and the tube does not feel heated.

Reaction 8: Zinc metal + Sulfuric Acid

Tiny small gray ball-shaped Zinc metal and clear liquid Sulfuric Acid mix to cause effervescence and bubbling, while the tube temperature feels heated.

Reaction 9: Magnesium metal + Hydrochloric Acid

Black-shaped Magnesium metal and clear liquid Hydrochloric Acid mix to cause the liquid to fuzz up, bubble, and heat up.

Reaction 10: Zinc metal + Copper (II) Sulfate

Dark gray Zinc metal and dark blue Copper (II) Sulfate mix, causing the liquid color to fade into a clear-ish color with no temperature change.
