A chemistry graduate student Is glven 250. mL of a 0.70M acetic acid (HCH,CO,) solution. Acetic acid is a weak acid with K=1.8x 10, What mass of NaCH,CO, should the student dissolve In the HCH,CO, solution to turn It Into a buffer with pH =4.747 2. You may assume that the volume of the solution doesn't change when the NaCH,CO, Is dissolved in It. Be sure your answer has a unit symbol, and round It to 2 significant digits.

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.
