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.

Transcribed Image Text:Some Basics regarding Chemical Elements:
A Chemical element as found on the Periodic Table of Elements (found on the Inside cover of your
text) is a pure substance which cannot be decomposed by chemical change.
The names of Elements are often abbreviated to simplify formulas using these elements. These
abbreviations are referred to as chemical symbols. For Hydrogen, the symbol "H'; for Oxygen, "O";
and for Carbon, "C". Sometimes two letters are necessary to distinguish between two or more
elements when the names of the elements begin with the same letter. For Example: Ca for Calcium,
Cr for Chromium, Co for Cobalt, Cl for Chlorine, etc. No symbols contain more than two letters and
the first letter is always capitalized. Some symbols are abbreviations of Latin names of elements (l.e.
Fe for iron; Latin, ferrum).
Each Element has an atomic number and an atomic weight. The weight is in relative terms as an atom
of each element is extremely small. As an example: Hydrogen, "H' has the atomic number of 1 and
an atomic weight of1.008, Calcium has the atomic number of 20, with an atomic weight of 40.08.
One atom of Calclum weighs approximately 40 times that of Hydrogen.
The following is a list of Elements commonly found in the soil or atmosphere and utilized by plants
for their growth processes. From the Periodic Table in your text, look up the Chemical Symbol, the
atomic number and the atomic weight.
