| Pour out 25 mL of 70% nitric acid into the beaker. This volume is enough to dissolve most packages and provides enough liquid to buffer the temperature. If a watch glass is available, put it on top of the beaker. This will create a reflux condenser that will reduce fumes and reuse evaporated acid. Note the pour spout of the beaker should keep the assembly from building up pressure. | Pour out 25 mL of 70% nitric acid into the beaker.
