Formulas of Common Acids and Bases

Formulas of Common Acids and Bases Acids and bases are used in many chemical reactions. They are responsible for most color change reaction and are used to adjust the pH of chemical solutions. Here are the names of some of the common acids and bases and the formulas associated with them. Formulas of  Binary Acids A binary compound consists of two elements. Binary acids have the prefix hydro in front of the full name of the nonmetallic element. They have the ending s include hydrochloric, and hydrofluoric acid includes: Hydrofluoric Acid - HFHydrochloric Acid - HClHydrobromic Acid - HBrHydroiodic Acid - HIHydrosulfuric Acid - H2S Formulas of Ternary Acids Ternary acids commonly contain hydrogen, a nonmetal, and oxygen. The name of the most common form of the acid consists of the nonmetal root name with the -ic ending.  The acid containing one less oxygen atom than the most common form is designated by the -ous ending. An acid containing one less oxygen atom than the -ous acid has the prefix hypo- and the -ous ending. The acid containing one more oxygen than the most common acid has the per- prefix and the -ic ending. Nitric Acid  - HNO3Nitrous Acid - HNO2Hypochlorous Acid - HClOChlorous Acid - HClO2Chloric Acid - HClO3Perchloric Acid - HClO4Sulfuric Acid - H2SO4Sulfurous Acid  - H2SO3Phosphoric Acid - H3PO4Phosphorous Acid - H3PO3Carbonic Acid - H2CO3Acetic Acid - HC2H3O2Oxalic Acid - H2C2O4Boric Acid - H3BO3Silicic Acid - H2SiO3 Formulas of Common Bases Sodium Hydroxide  - NaOHPotassium Hydroxide - KOHAmmonium Hydroxide - NH4OHCalcium Hydroxide - Ca(OH)2Magnesium Hydroxide - Mg(OH)2Barium Hydroxide - Ba(OH)2Aluminum Hydroxide - Al(OH)3Ferrous Hydroxide or Iron (II) Hydroxide - Fe(OH)2Ferric Hydroxide or Iron (III) Hydroxide - Fe(OH)3Zinc Hydroxide - Zn(OH)2Lithium Hydroxide - LiOH

Geology Week 2 DQ 1 - Essay Example This process enables creation of crustal material, thereby constituting this type of boundary. Transform plate boundary – Two tectonic plates move parallel to each other. They collide against each other during this movement. Earth disturbances occur for example earthquakes, leading to the formation of this boundary. Western and Eastern United States are a representation of active and passive continental margins (Rhodes & Perlman, 2001). In the light of plate tectonic theory, the Western continental margin is characterized by the occurrence of oceanic plates that result from the crashing activity of the continental edge. On the other hand, the Eastern United States continental margin is passive, meaning that it is not characterized by geological activities. Collision or subduction processes do not occur, and tectonic activity is therefore minimal (Rhodes & Perlman, 2001). As a result, extensive continental shelves emerge from erosion and weathering processes. The acceptance of plate tectonic theory based on magnetic anomalies and polar reversals followed studies and discoveries that evidenced the applicability of the theory. Historical and present continental distribution is attributed to the earth’s magnetic field (Rhodes & Perlman, 2001). Rock formation processes and plate tectonic movements have been consistently studied and proved, shaping the present geological structure in the light of the plate tectonic
