Chemists have defined the pH (Hydrogen Potential) of a solution by pH = -log[H+] where [H+] represents the concentration of the hydrogen ion in moles per liter. The pH scale ranges from 0 to 14 depending on a solution’s acidity or alkalinity. Values below 7 indicate progressively greater acidity, while above 7 are progressively more alkaline. Normal, unpolluted rain has pH of about 5.6. Since the pH scale is logarithmic, keep in mind that there is tenfold in hydrogen ion concentration for each pH unit. An environmental concern involves the destructive effects of acid rainfall ever had a pH of 2.7, what is the hydrogen ion concentration? A. 0.002 mole per liter B. 0.004 mole per liter C. 0.39 mole per liter D. 0.25 mole per liter
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.
