    Study Notes

    Acids and Bases Classification

    • HNO3: Classified as a strong acid, fully dissociates in aqueous solution.
    • HBr: Another strong acid, also completely ionizes in water.
    • H3PO4: Identified as a weak acid, partially dissociates in solution.
    • CH3COOH (Acetic Acid): A weak acid, known for its partial dissociation in water.
    • HCN: Considered a weak acid due to incomplete ionization.

    Strong Bases

    • LiOH: Recognized as a strong base, fully dissociates in solution.
    • Ba(OH)2: Another strong base that completely ionizes in water.

    Weak Bases

    • CH3NH2 (Methylamine): Classed as a weak base, does not fully dissociate in solution.
    • NH3 (Ammonia): A weak base, known for its partial dissociation and equilibrium establishment.

    Other Classifications

    • NaCl: Not classified as an acid or base; referred to as "other" due to its neutral nature in aqueous solution.

    Conjugate Acids

    • H2PO4- (Dihydrogen Phosphate): Conjugate acid is H3PO4 (Phosphoric Acid).
    • CO3^2- (Carbonate): Conjugate acid is HCO3- (Bicarbonate).
    • NH3 (Ammonia): Conjugate acid is NH4+ (Ammonium Ion).

    Reaction Quotient (Q) and Equilibrium

    • When K is small: Indicates a reaction that favors reactants over products.
    • When K is large: Suggests a reaction favoring the formation of products over reactants.
    • Q > K: Signifies that the reaction will shift towards the reactants, decreasing product concentration.
    • Q = K: Denotes that the system is at equilibrium and will not shift toward either reactants or products.
