Relative Strengths of Acids and Bases · Chemistry

2018-8-3 · where the concentrations are those at equilibrium. Although water is a reactant in the reaction, it is the solvent as well, so we do not include [H 2 O] in the equation. The larger the K a of an acid, the larger the concentration of H 3 O +. and A − relative to the concentration of the nonionized acid, HA. Thus a stronger acid has a larger ionization constant than does a weaker acid.

Acid-Base Pairs, Strength of Acids and Bases, and pH

Acids and bases in the Brnsted model therefore exist as conjugate pairs whose formulas are related by the gain or loss of a hydrogen ion. Our use of the syols HA and A-for a conjugate acid-base pair does not mean that all acids are neutral molecules or that all bases are negative ions. It signifies only that the acid contains an H + ion that isn''t present in the conjugate base.

Stoichiometric Calculations

2019-4-29 · This equation states that 1 iron (Fe) atom will react with two oxygen (O) atoms to yield 2 iron atoms and 3 oxygen atoms. (The subscript nuer, such as the two in O 2 describe how many atoms of an element are in a molecule.) This unbalanced reaction can''t possibly represent a real reaction because it describes a reaction in which one Fe atom magically becomes two Fe atoms.
