disposal bucket. Repeat for the other two reagents. 4. When you have completed the three reagents, return to the Stockroom. Double-click on each bottle to return it to the shelf. Obtain three more samples (two salts and one solution): KNO3, NH4Cl, and NH3and return to the laboratory. Follow procedure #3 for NH4Cl, and KNO3. For the NH3solution, complete the following procedure: Place a beaker on the stir plate. Pick up the NH3solution from the stockroom shelf, drag it to the 25 mL graduated cylinder, and let go to fill the cylinder. The solution bottle will automatically go back to the stockroom shelf. Drag the 25 mL graduated cylinder to the beaker on the stir plate and drop it to transfer the solution into the beaker. Place the conductivity meter probe in the beaker and record the conductivity in the data table. 5. When you have completed the three reagents, return to the Stockroom. Double-click on each bottle to return it to the shelf. Obtain two more samples: HCland HCN. Measure the conductivity of each solution following procedure #4 and record the conductivity in the data table.
