CHEM 103 Lecture Notes - Lecture 4: Oxidation State, Solution
Document Summary
Matter is neither created or destroyed in ordinary chemical reactions. Leo say ger (lose electron oxidation, gain electron reduction) Polyatomic ions: 2 or more atoms with an electrical charge. Binary molecular compounds: molecules with only two elements in them. Hydrogen combined with every non metal except noble gases. The number of atoms in the beginning and end must be equal. Cations and anions separate when he ionic compounds dissolve. Electrolytes: substances that produce an electric current when dissolved in water. Includes a transfer of positive hydrogen ions from one reactant to another. Bases cause etals to form insoluble compounds. Share similar properties with positive hydrogen atoms. At least 1 ion formed by acids include a positive hydrogen atom. A reaction that occurs when a compound is formed with the removal of ions. Hydrogen and hydroxide ions from water and salts. Acids reacting with metal carbonates lead to gas to form. Metal sulfites lead to a foul smelling gas.
