Quick Quiz

  • What are the 6 strong acids??

  • What are the 6 strong bases??




Define
Define

  • A Lewis Base

  • A Bronsted Lowry acid

  • An Arrhenius Acid


15 4 relative strengths 659
15.4 Relative Strengths (659)

  • Table 15.2 p660 compares relative strengths of acids and bases.

  • A reaction normally goes in the direction of the weaker acid & base.

  • The strongest acids have the weakest conjugate bases and vice versa.


Predict the direction of the reaction based on the table 15 2 661
Predict the direction of the reaction based on the Table 15.2: (661)

  • SO4-2 + HCN  HSO4- + CN-

  • H2S + C2H3O2- HC2H3O2 + HS-



Polarity
Polarity 15.2: (661)

  • The more polar bonds allow protons to be removed easier increasing the acid strength.

  • Across a period electronegatives increase, increasing the polarity and acid strength.

  • H2O<HF


Bond strength
Bond strength 15.2: (661)

  • The larger the atom is which H is bonded to, the weaker the bond and thus a stronger acid.

  • Down a family the radius increases, decreasing the bond strength and increasing the acid strength.

  • HF<HCl<HBr<HI


Oxoacids h o y
Oxoacids 15.2: (661): H – O – Y

  • For a series of oxoacids of the same structure, differing only in the atom Y, the acid strength increases with the electronegativity of Y.

  • HIO<HBrO<HClO


Multiple oxygen atoms
Multiple oxygen atoms 15.2: (661)

  • For a series of oxoacids, (HO)mYOn, the acid strength increases with n. The more O’s the stronger the acid.

    • HClO< HClO2< HClO3< HClO4


Polyprotic acids
Polyprotic Acids 15.2: (661)

  • Strength decreases as protons are lost.

  • HPO4-2 < H2PO4- < H3PO4
