A student determines that an aqueous solution that contains 0.254 M sodium acetate and 0.417 M acetic acid, also has a H3O+ concentration of 3.90×10-5 M. Based on these data, calculate the value of the equilibrium constant K for the equilibrium: CH3COOH(aq) + H2O --- H3O+(aq) + CH3COO-(aq) (1) as is usually done, without the inclusion of water in the expression for K: K = (2) for comparison, with the inclusion of water in the expression for K: K =
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.
Bronsted Lowry Base In Inorganic Chemistry
Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.
