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.
The pH scale is only valid for water. Explain.
pH scale is only valid for water.
Water is made up of equal number of H+ and OH- ions.
H+ + OH- -------> H2O
As pH is actually a measure of relative amount of free hydrogen and hydroxyl ions in the water. Water that has more free H+ ions is acidic, whereas water that has more free OH- ions is basic.
Water with equal number of H+ and OH- ions is neutral.
The pH of water is affected by chemicals present in water. It is an important indicator of chemical change in water.
Chemically, pH = -log [H+]
