The iron content of iron ore can be determined by titration with standard KMNO, solution. The iron ore is dissolved in HCI, and all of the iron is reduced to Fe2+ ions. This solution is then titrated with KMNO̟ solution, producing Fe3+ and Mn2+ ions in acidic solution. What is the mass of KMNO, solid, in grams, to 4 prepare 1.000 L 0.02 M standard KMNO, solution? It turns out that 38.37 mL of 0.0198 M KMnO̟ is required to titrate a solution made from 0.6128 g of iron ore. What is the mass percent of iron in the iron ore?
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.
