Carbonic acid (H2CO3) is a diprotic acid. For the titration of 50.00 mL of 0.0100 M H2CO3 with 0.0100 M NaOH, calculate the pH of the solution (i) before the addition of any NaOH; (ii) at the first endpoint where [H+] ~ (K1K2) 1/2;
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.
