How do I calculate the pH of a 0.093 M NaF solution, where the Ka for HF = 7.1 x 10^-4? HBrO H + BrO Given the pH is 4.48, the concentration of H is: Given the initial concentration of the acid ( Ca) is 0.55 M, we can calculate the acid dissociation constant ( Ka) using the following expression. Find th. The H-O bond is weakened or increasingly polarized by the additional oxygen atoms bonded to the central bromine atom in HBrO3. K_a for hypobromous acid, HBrO, is 2.0 times 10^-9. Q:What is the conjugate base of HClO4, H2S, PH4 +, HCO3 - ? Ka of HBrO is 2.3 x 10-9. Conjugate acid of HCO, A:Proton (H+)donar is Bronsted acid. (Ka = 2.9 x 10-8), Calculate the pH of a 0.285 M HClO solution. HBrO, Ka = 2.3 times 10^{-9}. Round your answer to 2 significant digits.
