Question 1.
What does spectrophotometry measure?
Show hintHide hint
Think about what properties of light are related to concentration.
Question 2.
Why is it important to calibrate conductometry measurements?
Show hintHide hint
Consider how measurements relate to known values.
3Question 3.
What does spectrophotometry help measure?
- pH levels
- Absorbance of light
- Temperature changes
Show hintHide hint
Consider light characteristics.
4Question 4.
True or False: Conductometry can be used to monitor non-ionic reactions.
- True
- False
Show hintHide hint
Think about what conductivity relies on.
Question 5.
You are monitoring a reaction using both spectrophotometry and conductometry. The absorbance of the product is found to increase while conductivity remains unchanged. Discuss possible reasons for this observation.
Show hintHide hint
Consider the chemical nature of both the product and the reactants.
Question 6.
An experiment involves a reaction that produces two different ionic products with distinct conductivity values. If the initial conductivity is measured at 0.5 mS/cm and the reaction generates ions that increase conductivity to 1.5 mS/cm, calculate the total change in conductivity and identify the implications this has on the reaction rate.
Show hintHide hint
Focus on the relationship between concentrations of ions and conductivity.
