Discussion Question 1 Define an acid, base, and salt as they apply to chemistry. Acid When acid is dissolved into water it produces a substance of H+ ions. Acids are a substance containing hydrogen in the chemical form of Sulphuric (H2SO4), hydrochloric (HCI), and nitric (HNO3). Although, not all substances containing hydrogen are acids it can also contain water (H2O) and methane (CH4). The three acids above when reacting with water results as HCI→ (H2O)→ H+→ CI-, H2SO4→ (H2O)→ 2H+SO4^2-, and HNO3→ (H2O)→ H+NO3-. Nitric, sulphuric, and hydrochloric acids are considered to be inorganic. However, there are also organic acids as well. Acetic acids are typically found in vinegar. Its chemical formula consists of CH3Co2H. Hydrogen atoms do not always give H+ ions when in water. For instance, only the hydrogen attaches to the ozygen yielding a H+ ion forming a chemical formula such as CH3CO2H→(H2O)→ H+ CH3CO2-. Most acids typically illustrate an acidic property when water is involved. Acids are know to cause corrosive, brining of the flesh, and is powerful enough to dissolve metal. Bases and Alkalis A base is a substance that produces OH- ions when combined with water. They are typically metal hydroxides (MOH). Examples consist of calcium hydroxide (NaOH) and calcium hydroxide (Ca(OH)2). An alkali is known as the solution of a base when in water. For instance, when the two bases are combined the reaction results in the following NsOH→ Na+ + OH- and Ca(OH)2→ (H2O→ Ca2+ + 2OH-.
