In order to quantify the amount of dissolved oxygen in water, the Winkler method could be used. The first step of this method is the standardization of a sodium thiosulfate solution. During a standardization experiment, a student used a 3.200×10 M potassium iodate solution to titrate 20.00 mL of the sodium thiosulfate solution. The student found that 14.40 mL of the potassium iodate solution were needed to reach the equivalence point. Show the reaction taking place and determine the concentration of the sodium thiosulfate solution?
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.
