The concentration of Ca ion in a town’s water supply is 0.0020M (this water is referred to as hard water because it contains such a large concentration of Ca2+. Suppose the water is to be fluorinated by the addition of NaF for the purpose of reducing tooth decay (the most common health policy in most of the US). What is the maximum concentration of fluoride ion that can be achieved in the water before precipitation of CaF2 begins?
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.
