- Solved HELP! Part B. The water chemist waits until | Chegg. com
Question: HELP! Part B The water chemist waits until returning to the laboratory to fix the water sample for the dissolved oxygen analysis Will the reported dissolved oxygen concentration be reported as too high, too low, or remain unchanged? Explain Part B 3 A solution of MnSO4 is added to fix the dissolved oxygen in the collected sample
