Question

a. A solution of HNO, has a pH of 3.63. What is the molarity of the solution? Molarity = b. A solution of HNO3 has a pH of 5.31. What is the molarity of the solution? Molarity = c. A solution of HNO3 has a pH of 1.24. What is the molarity of the solution? Molarity =

Answer 1

please forget first line of the solution.

if the solution is diluted to 10 times. TAS HNO3 completely dissociates ) I So, the concentration of hy / HNO3 F itt twoo I will be concentration of HNO3 w ptt = - log [H+] for Strong acidic Solution As HNO is a acidic So, it follow this. pH == log tut we know a) at pH = 3-63; TH+7= 2:34x1074 = anti log (-3663) = 0.000234 m) So. the molarity of the Solution = 0.000 2346). b) ÞH = 5,3 [H+) - 5.01810-06 = 0.00000501(4) Molarity of the solution =0.00000501(M) C) pH = 1:24 [14] = canti log E}*) -0.0575M) .:, Molarity of the solution - 010575 (M)
