Question #7 Lareina the laboratory technician is given the task of making a solution containing HOBr ( Ka = 2.8 x 10-9) and KOBr and testing its behavior when strong acid or base is added to it. Part 1 First, Lareina combines 90.54 g KOBr and 255 mL of 1.30 M HOBr, and adds enough distilled water to make 800 mL of solution. What is the pH of this solution? pH solution Part 2 = Next, Lareina adds 12.0 mL of 2.20 M HNO3 to 350 mL of the solution made in Part 1. What is the pH of the solution after the HNO3 is added? pH after HNO3 added Part 3 = Finally, Lareina adds 12.0 mL of 2.20 M NaOH ito 370 mL of the solution made in Part 1. What is the pH of the solution after the NaOH is added? pH after NaOH added =

FOLLOW-UP QUESTIONS 1. A certain soft drink was analyzed and found to contain 0.080MH. Other ingredients of the drink include sugar or, in the diet form of the drink, an artificial sweetener. What property of this acid solution is overcome by using sugar or sweetener? 2. Every day, a manufacturing plant produces 5.0 x 103 L of NaOH waste of molarity 0.030 M. In order to comply with environmental regulations, this NaOH must be neutralized before being discharged as effluent. What mass of concentrated HCl will be required to neutralize it? ([HCI] = 12M; density = 1.2 kg/L) 4. Why would it be difficult to measure e concentration of acid in red wine or in a cola-type drink using the method in Part V? How could you overcome this difficulty? 5. There are some titrations in which the endpoint is obtained by measuring the electrical conductivity of the solution and watching for the point at which the conductivity is at a minimum. Such a titration is called an electrometric titration. An…

Order these chemical species by increasing pH of an 0.1 M aqueous solution of each. That is, imagine making an 0.1 M solution of each species. Select 1 next to the species that makes the solution with the lowest pH. Select 2 next to the species that makes the solution with the next higher pH, and so on. Notice that some of the rankings have been filled in for you already. Also notice that water is on the list. For that particular case, just compare the pH of pure water to the pH of the other solutions. Note for advanced students: for all charged species, you may assume the necessary counterions act as neither acids nor bases. relative pH of 0.1 M aqueous solution species ? 103 |(Choose one) ▼ OH |(Choose one) ▼ H,0 4 HC,04 6.
