Silver Nitrate Day One Lab

OBJECTIVE

• Observe evidence of a chemical reaction.

INFO

• Cu + 2AgNO₃ --> 2Ag + Cu(NO₃)₂

MATERIALS

• about one to two grams AgNO₃
• 250-mL Beaker A
• about a foot of copper wire
• mass balance

DATA

1. mass of Beaker A = g
2. mass of Beaker A & AgNO₃ = g
3. mass of Cu wire before reaction = g
4. mass of AgNO₃ (b - a) = g

PROCEDURE

1. wear splash-guard goggles
2. cut 1 ft of Cu wire and mass to the thousandths place
• coil around pen or pencil
3. wash, dry, and label Beaker A (250 mL)
4. mass out Beaker A to thousandths place
5. add AgNO₃ to Beaker A & mass out dry AgNO₃

*** BACK TO DESKS ***

6. half fill Beaker A with distilled water
• leave the water on the back counter
7. wash & dry a stirring rod, then dissolve the AgNO₃
• important:

o keep AgNO₃ off of clothes & skin

o wash and dry again the stirring rod

8. place the wire into Beaker A & observe
9. place Beaker A, AgNO₃, and Cu on back counter

OBSERVATIONS

• record evidence for a chemical reaction
