I need help answering these questions, based off my graphs and the conductivity of the three acids: acetic: 761 Metalic: 2953 HCL: 25560

Examine your values for the % ionization at 0.1M.  Is there a difference between the acids?  Do the conductivity measurements correlate to these % ionization numbers?  Explain. 2pts.

 

Examine the % ionization as a function of the concentration for these acids.  Describe in detail what you observe.  What differences do you see between strong and weak acids?  NOTE: A % Ionization greater than 100% is not possible and should be assigned a value of 100%.  2pts.

 

Based on what you know about LeChatelier’s Principle, explain why you see a much larger increase in percent ionization for the weak acids as they become more dilute. 2pts.

 

How do your experimental pH values compare to the theoretical ones you calculated?  Explain any similarities or differences.  2pts.

 

Based on the conductivity readings of the following acids, classify them as strong or weak acids. 2pts.

Vinegar – 689mS/cm, Lemon Juice – 735 mS/cm, Toilet Bowl Cleaner –21,321 mS/cm, Soft Drinks – 525 mS/cm
