NettetCHEM 301 - Assignment #2 SOLUTIONS 1. Hypochlorous acid (HOCl) is a considerably more effective dis-infectant than it’s conjugate base (OCl). What concentration (as mg/L Cl2) needs to be added to a water sample naturally buffered at pH 7.8, in order to achieve a HOCl concentration of 1.0 mg/L (as Cl2)? pKa (HOCl) = 7.25 Solution: The relevant …

NettetH 2 S Hazards and Symptoms Extremely toxic (almost as toxic as Hydrogen Cyanide) and 5 to 6 times as toxic as Carbon Monoxide, H 2 S can be only smelt at low concentrations (1-50 ppm). Beyond 50 ppm, the sense of smell is lost after about 15 minutes of exposure. Therefore DO NOT DEPEND ON SMELL TO DETECT H2S. Nettet3. des. 2015 · Rough order of acidity: HI> H_2SO_4 >HNO_3>H_3PO_3>HF. HI, H_2SO_4, and HNO_3 are reasonably regarded as strong acids. As physical scientists, however, we should look at actual measurements, namely the pK_a values of each acid in water. HI, pK_a = -10 (estimated) H_2SO_4, pK_(a1) = -3, pK_(a2)=1.99 HNO_3, pK_a …
