Answer to Question #168123 in General Chemistry for Olivia Porter

Question

what is the Kb of the bromate ion if a 0.350mol/L solution of CsBrO3 (aq) has an equilibrium concentration for [HBrO3] and [OH-] of 3.56x10 -5 mol/L

Answer 1

Given:

[HOCl]=0.199

[H₃O⁺]=8.4 x 10^-5

[OCl-]=8.4 x 10^-5

Step 1: Use the formula using the concentration of [H₃O⁺] to find pH

pH=−log[H3O+]=−log(8.4x10

−5)=4.08(21)
