Lab 5.1 (continued) 3. Collecting and Interpreting Data of the three metals, Pb, Cu, Zn, which is the most active? zn,zinC 4. Collecting and Interpreting Data of the three metals, Pb,Cu,Zn, which is the least active? Cu, copper. 5. Drawing a Conclusion Cite the experimental evidence that indicated which of the three metals, R. Cu, Zn. was most active and which metal was least active. 6. Sequencing Arrange the metals Pb,Cu,Zn,Ag, and Mg in order of activity, from least active to most active. 7. Sequencing is hydrogen more active or less active than Cu, Zn, Ag, and Mg? tess active. 8. Drawing a Conclusion Cite the experimental evidence used to establish the location of hydrogen in this activity series. 9. Predicting What additional test would be necessary to establish the exact position of hydrogen in this activity series? 10. Error Analysis Compare your activity series to one in a textbook or reference book. Explain any differences. Real-World Chemistry 1. Explain why acids are not stored in steel containers. 2. Sodium is a very active metal. Explain why sodium is only found in compounds in nature. 3. Explain why magnesium metal, rather than copper metal, might be used to study the effect of concentration of hydrochloric acid on rates of reactions
