The correct name for HIO2 is _____ asked Sep 12, 2016 in Chemistry by Stephanie. Now you can substitute the value of x into the last line of the table written in Step 1 to find the concentrations of species. Best answer. University of Florida. or x 2 ~ 1.4 x 10-5 x 0.10 = 1.4 x 10-6.Hence, x ~ 1.2 x 10-3 = 0.0012 .At this point, you check that the assumption that 0.10 - x ~ 0.10 is valid.NB. Greater the Ka value greater is the acid strength. Answer. HBrO2 I believe is actually stronger because the O will pull the Br away from the H more so then the O will pull the Cl away from the H. Always the more electro neg atom is the strongest acid. c) HIO2 < HClO3 < HIO3 < HClO4. > 1, then the acid strength of acid and bromic acid of 10cm3! Hclo4 < HIO2 < HClO4 b. HF c. HBr d. HI e.
