Rank the following organic molecules in order of increasing acidity.
Why is H2S a stronger acid than H2O when the conjugate base of H2O should be more stable than the conjugate base of H2S (due to O being more electronegative than S)?

Titrations. Determine if the equivalence point (from the acid/base titration curve) will be equal to pH 7, will be lower than pH 7, or will be greater than pH 7 in the solutions below. Strong acid/strong base Weak acid/strong base Strong base/weak acid Rank the acids in order of increasing acidity: H2O, H2S, H2Se H3PO4, H2PO2, H3PO5
1) Predict relative acidity. Rank in order of increasing acidity (be able to explain): a) CH3CH2SO3H, b) CH3CHClCO2H, c) CH3CH2OH, d) ClCH2CH2CO2H, e) CH3CH2CO2H 2) Predict relative acidity. Rank the following in order in increasing acidity: NH3, H2SO4, CH3OH, CH3CO2H, H3O+, H2O Hint: think of what would produce the most stable species after deprotonation. A good acid would gladly lose a proton (to form a stable conjugate base). 3) Predict relative basicity. Rank the following in order in increasing basicity:...
