No credit will be given for this lab report if the Data section is not completely filled out and if the required photographs are not received. At least one photograph must show the student’s face.
NOTE: This experiment is rather lengthy. Plan accordingly.
1. Define strong electrolyte, weak electrolyte, nonelectrolyte, acid, base, salt, strong acid, weak acid, strong base, weak base, and neutralization reaction.
2. Compare and contrast the chemical reactions of strong and weak acids and strong and weak bases.
3. Define pH and the pH scale and understand how pH relates to the acidity of a substance.
4. Classify substances as acidic, basic, or neutral using a pH indicator.
5. Determine if a neutralization reaction has occurred.
6. Classify common household substances as acidic, basic, or neutral using a pH indicator.
7. Balance neutralization reactions.
8. Write net ionic equations for neutralization reactions.
Please complete the entire experiment as instructed in the lab manual except for any modifications noted below. Fill out the report below and submit it me electronically via Canvas. Email the digital photographs to me at email@example.com .
NOTE: Before answering the questions, you may want to review the tutorials on balancing chemical equations and writing net ionic equations that are in the Canvas course site.
DATA AND OBSERVATIONS (25 points total)
You need four digital photographs. At least one should show your face (with safety glasses) as you perform the experiment. Include these photographs:
1. Testing the sodium hydroxide with BTB (make sure I can see the sodium hydroxide after the BTB is added)
2. Well plate after completion of data table 1 (make sure I can see the plate and its contents clearly)
3. Well plate after completion of data table 2 (make sure I can see the plate and its contents clearly)
4. Testing a household substance
