20. Solutions can be analyzed for sulfate content using gravimetric analysis by precipitation of sulfate ions as BaSO. (Kip = 1.08x10¹0). If a solution has a [SO] of 2.10x10 M. what [Ba 1, in M, will be required to initiate precipitation? a. 2.10x10¹ b. 5.14x107 C. 2.27x10¹1 d. 1.04x10 441x10³ e
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.
