A)9.9 10-2 B)1.2 10-5 C)2.8 10-12 D)6.9 10-9 E)1.4 10-10 16) 17)The pH of a 0.55 M aqueous solution of hypobromous acid, HBrO, at 25.0 C is 4.48. (Ka = 2.5 x 10-9) name: Given that acetic acid hasKa= 1.8 x 105, what is the pH of a solution that contains the molar ratio of conjugate base-to-acid: [CH3CO2]/[CH3CO2H] = 1/10?
