Lareina the laboratory technician is given the task of making a solution containing HOBr ( Ka KOBr and testing its behavior when strong acid or base is added to it. Part 1 Question #7 = 2.8 × 10-9) and 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 =
