Acids and bases - Essay ExampleAcids and bases exhibit contrasting sets of properties that classify them along the pH scale. Concentration of hydrogen ions in aqueous caustic solutions classifies the substances bellow pH value of seven, neutral state, while hydroxide ions concentration classifies alkaline solutions above seven in the pH scale. Presence of cat ions and anions in the basic and acidic solutions, as chemical properties, allows for reaction between acids and bases to form ionic salts and covalently bonded water molecules. Acids also react with metals and carbon copyates to form salts together with hydrogen gas and water and carbon (IV) oxide respectively (Moore, p. 171 CK-12, p. n.p.).Hydrochloric acid for utilisation reacts with sodium hydroxide to yield sodium chloride and water. Similarly, zinc reacts with hydrochloric acid to form zinc chloride and hydrogen gas (Moore, p. 171 CK-12, p. n.p.).Acids and bases have different sets of properties that can be used to inv estigate them. Effects of the properties such as the corrosive nature of acids can physically indicate their presence. Acids also have a characteristic sourness and turn a litmus paper to red, a feature that used to test for acidity (Files, p. 1). Moore explains that acids have a corrosive military issue that burns the skin. The chemicals also react with metals to form salt and hydrogen as shown bellow.Similarly, acids react with carbonates to form salt, water, and carbon (IV) oxide and with bases to form salt and water. Sodium hydroxide for example react with hydrochloric acid forming sodium chloride and water while hydrochloric acid reacts with calcium carbonate to form calcium chloride, carbon (IV) oxide and water as shown bellow.Bases however, taste bitter, tonicity slippery on the skin, react with oil and greases, react with litmus paper and turn it blue and form salt and water upon reaction with
