4. Cobalt phosphate (Cos(PO4)2, 15.38 g. 366.75 g/mol) and chromium(III) chloride (CrCl3, 3.46 g, 158.35 g/mol) were added to enough water to make a 100 mL solution. When equilibrium was reached, the equilibrium concentration of cobalt(I) was [Co¹*]eq = 0.0172 M. Co2+ (aq) + Cr³+ (2 (aq) K₁ K.1 co (aa) + Cr4+ (aq) K 1.184 x 103 a. Calculate the equilibrium concentrations of the ions in the reaction. b. The equilibrium was stressed by adding chromium(IV) oxide (CrO₂, 2.134 g. 84.00 g/mol) to the solution. Determine the concentration of Co" after equilibrium was re-established. (Assume no change in solution volume with the CrO₂ addition.)
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.
