Be sure to answer all parts. Chloroacetic acid, CICH,COOH, has a pK, of 2.87. What are [H3O+], pH, [CICH,C00-], and [CICH,COOH) in 2.25 M CICH,COOH? [H30+] = M [CICH,C00-] = [CICH,COOH)= pH=
An acid-base indicator, Hin, dissociates according to the reaction shown in an aqueous solution. K. HIn HIn(aq) In (aq) + H+ (aq) The protonated form of the indicator, HIn, has a molar absorptivity of 2089 M-.cm-1 and the deprotonated form, In, has a molar absorptivity of 14310 M-1.cm-1 at 440 nm. The pH of a solution containing a mixture of HIn and In is adjusted to 6.20. The total concentration of HIn and In is 0.000200 M. The absorbance of...
