Lareina the laboratory technician is given the task of making a solution containing HOBr ( 2.8 x 10 ) and KOBr and testing its behavior when strong acid or base is added to Ka = it. Part 1 First, Lareina combines 81.42 g KOBr and 245 mL of 1.70 M HOBr, and adds enough distilled water to make 950 mL of solution. What is the pH of this solution? pH solution = Part 2 Next, Lareina adds 12.0 mL of 2.40 M HNO, to 385 mL of the solution made in Part 1. What is the pH of the solution after the HNO, is added? pH after HNO, added = Part 3 Finally, Lareina 18.0 mL of 2.10 M NaOH ito 375 mL of the solution made in Part 1. What is the pH of the solution after the NaOH is added? pH after NaOH added =
