Understanding Hydrogen Ion Formation and Properties of Lead Nitrate

Explore the chemistry of hydrogen ion formation through a detailed diagram. This activity involves hypothesis development regarding whether Lead Nitrate (Pb(NO3)2) is an acid or a base, and what its pH could be. Utilize different pH indicators like Universal Indicator, Bromothymol Blue, and Sodium Hydrogen Carbonate to analyze Pb(NO3)2. Document observations in a data table, draw diagrams, and conclude based on scientific reasoning the properties of Lead Nitrate. This understanding can have practical implications in various chemical applications.

Presentation Transcript

  1. Warm up Draw a diagram that shows how a hydrogen ion is formed

  2. Warm up answers

  3. question Is the chemical an acid or a base and what is its pH? Lead Nitrate A. Universal Indicator Solution B. Bromothymol blue C. Sodium Hydrogen Carbonate

  4. hypothesis Learn a little about each chemical before you make a hypothesis

  5. Background information Lead Nitrate http://en.wikipedia.org/wiki/Lead(II)_nitrate Universal Indicator Solution http://en.wikipedia.org/wiki/Universal_indicator Bromothymol blue http://en.wikipedia.org/wiki/Bromothymol_blue Sodium Hydrogen Carbonate http://en.wikipedia.org/wiki/Sodium_hydrogen_carbonate Now make your hypotheses (plural of hypothesis)

  6. methods Pb(NO3)2 with Univerasal Indicator Solution Pb(NO3)2with Bromothymol blue Pb(NO3)2with Sodium Hydrogen Carbonate Use other indicators if needed

  7. results Record your observations in a data table. Draw a picture (or use a photo), and write a description

  8. conclusion Is Pb(NO3)2 an acid or a base? What is its pH? Scientifically, what is the reason for these observations?

  9. Cool down Why is it important to understand what the properties of Pb(NO3)2 are? What is a creative way you could apply what you learned in class today?
