Chemistry Chapter 14
Name the following acids: HCLO2
Chlorous acid
What makes an acid weak?
A poor donor, stable. Low ionization when placed in water, and doesn't ionize 100% in water.
Name the following acids: H2S
Hydrosulfuric acid
Name the following acids: HNO2
Nitrous acid
Define Lewis acids and bases and give 2 examples of each:
Lewis Acid: Is an atom, ion, or molecule that accepts an electron pair to form a covalent bond [Ex. BF3. AlCl3 and any cation (H+)] Lewis Base: Is an atom, ion or molecule that donates an electron pair to form a covalent bond [Ex. NH3, any anion, water when it forms the hydronium ion]
Define a weak base and give 3 examples
More polarized and less likely to move. Its more stable; the hydrogen is hard to move. The weak acceptor of H+. [NH3, any conjugate base of any weak acid]
In the reaction NH3 + H20 -> NH4 + OH ; explain which of the three definitions of acids and bases that NH3 and H2O meet
NH3 : All of them (OH Producer, H+ acceptor, Lewis Base) H2O : Only Bronsted-Lowry just H+ donor
Name the following acids: H3PO4
Phosphoric acid
Explain the difference between a strong acid an a weak acid. Which acid exists in the highest concentration and why?
Strong acid is unstable/reactive, meaning the Hydrogen is easy to move. Weak acid is stable/nonreactive, meaning the Hydrogen is harder to move.
Name the following acids: H2SO4
Sulfuric acid
Identify the Lewis Acid and base in the following reaction: Cl + BF3 -> [BF3Cl]
The Cl is a Lewis base. the BF3 is Lewis acid.
A conjugate acid is the species that...
is formed when a Bronsted-Lowry base gains a proton
