An acid-base indicator, HIn, dissociates according to the reaction shown in an aqueous solution. K₁. Hin HIn(aq) The protonated form of the indicator, HIn, has a molar absorptivity of 3045 M-¹-cm-¹ and the deprotonated form, In, has molar absorptivity of 20860 M-¹-cm-¹ at 440 nm. The pH of a solution containing a mixture of HIn and In is adjusted to The total concentration of HIn and In is 0.000177 M. The absorbance of this solution was measured at 440 nm in a 1.00 c cuvet and was determined to be 0.770. Calculate pK, for HIn. In (aq) + H+ (aq)
Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
