1) 2)
2,4-Dichlorophenoxyacetic acid (Hdca) is a common herbicide that is used to treat broad leaf weeds. It is also one of two herbicides that made up Agent Orange which was used extensively during the Vietnam war to defoliate trees and bushes. Hdca behaves as a weak Acid and has a Ka - 1.86 x 10-3 at 25°C. Consider when 20.0 mL of 0.200 M Hdca (aq) is titrated with 0.400 M KOH Write the acid/base neutralization reaction that occurs...
