40.6.2. Laboratory Analysis

Try these first

1. 1.

   What is titration used for?

   Hint

   Remember it involves adding a reagent to reach a color change.

2. 2.

   What does AAS measure?

   Hint

   Think about how measurement is done using light absorption.

3. 3.

   What is the purpose of titration in laboratory analysis?

   • To determine water temperature
   • To assess color intensity
   • To measure solution concentration

   Hint

   Think about how it helps in quantifying ingredients in a mixture.

4. 4.

   True or False: Ion chromatography is used for measuring the temperature of water.

   • True
   • False

   Hint

   Remember what aspects of water it provides insight into.

5. 5.

   You are tasked with analyzing a water sample suspected of having high carbonate levels. Explain the steps to perform a titration to find out the carbonate concentration, including what equipment you would use.

   Hint

   Visualize the experiment step by step and think about what happens at each phase.

6. 6.

   Discuss the potential environmental and agricultural effects if high levels of lead were discovered through Atomic Absorption Spectrometry in irrigation water. What recommendations would you make to farmers?

   Hint

   Consider the cascading effects on the ecosystem when focusing on agricultural implications.
