N-nitrosodimethylamine (NDMA) is a suspected carcinogen that can form via reactions
between dimethylamine (DMA) and monochloramine (NH2Cl). The relevant elementary
reactions and the corresponding rate constants are as shown below.
Reaction
Rate constant (M¹s¹)
DMA + NH2Cl = DMCA + NH3
k =1.4×10-1, kr = 5.83×10-3
1.28×10-3
DMA + NH2Cl → UDMH
UDMH + NH2Cl → NDMA
->
1.11×10-1
If the initial concentrations of DMA and NH2Cl are given, you should be able to predict the
concentrations of all species at any given reaction time. Please write down the rate equations
for DMA, NH2C1, DMCA, UDMH and NDMA.

- You wish to add enough NaOCl (sodium hypochlorite) to a 150 m³ swimming pool to provide a dose of 5.0 mg/L TOTOCI as Cl2. (a) How much NaOCI (kg) should you add? (Note: the equivalent weight of NaOCl is based on the reaction: NaOCl + 2H + 2 e→CI + Na +H₂O.) (10 pts) (atomic weight: Na 23, O 16, C1 35.5) (b) The pH in the pool after the NaOCl addition is 8.67. To improve disinfection, you want at least 90% of the TOTOCI to be in the form of HOCI (pKa 7.53). Assuming that HOCI/OCI is the only weak acid/base group in solution, what volume (L) of 10 N HCl must be added to achieve the goal?
