Onsider the reaction of peroxydisulfate ion (s2o2−8) with iodide ion (i−) in aqueous solution: s2o2−8(aq)+3i−(aq)→2so2−4(aq)+i−3(a q). at a particular temperature the rate of disappearance of s2o2−8 varies with reactant concentrations in the following manner:

The following questions a24 - a26 relate to 100 ml of 0.0150 m solution of benzoic acid (c6h3cooh). ka(c6h3cooh) = 6.4 x 10^-5. what is the ph of the solution after the addition of 1 x 10^-3 moles of naoh? you may assume no volume change to the solution upon addition of the naoh.
