Concept explainers
Interpretation:
The reason due to which an acid cannot be turned into a base by diluting with water needs to be explained.
Concept introduction:
When an acid solution is diluted the concentration of the acid as well as the concentration of H+ decreases.
Answer to Problem 2E
Dilution of acid can decreases the hydrogen ion concentration but the solution remains acidic in nature.
Explanation of Solution
When an acid solution is diluted then the acidic strength of the solution decreases. When large amount of water is added,the presence of an acid in certain volume of solution is almost negligible. Thus, this highly diluted acid solution can have pH value slightly less than 7. Thus, dilution of acid can decreases the hydrogen ion concentration but the solution remains acidic in nature.

- All structural types of Boron hydrides exhibit B-B, B-H-B and B-H bonds. Correct?arrow_forwardN-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.arrow_forwardYou 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? (15 pts) Note that part a) is a bonus question for undergraduate students. If you decide not to work on this part of the question, you many assume TOTOCI = 7×10-5 M for part b).arrow_forward
