The pH of an aqueous solution of pyridine (C5H5N) is 10.0 at room temperature. What is the initial molar concentration of C5H5N, if its base ionization constant is: Kb = 1.7×10–9?
The base constant for ammonia, NH3, is Kb = 1.8 x 10-5. A solution was made up with ammonium chloride so that (NH4Cl] = 0.250 M and ammonium ion is a weak acid. What will be the pH of this solution? (The chloride ion is a spectator ion; it is the conjugate base of a strong acid, and so it has no acidic or basic contribution to the solution pH.)
How do I calculate pH of a salt? for example in 0.10 M NaClO4(aq)?
An organic acid(HA) has a molecular weight of 100. g mol^-1, a Kow=5.6 and a Ka=2.7x10^-2. If originally 2.0g of the acid is dissolved in 100mL of octanol (there is no dissociation in octanol), which is then placed in contact with 100mL of water, what will be the pH of the water? (consider the equilibrium processes to be sequential and unrelated chemically)
CH3CH2COOH Draw the Lewis structure of the acid and mark the acidic hydrogen with an asterisk (*). Draw a Lewis structure of the conjugate base of the acid. Suppose the acid is neutralized with a strong base. a) Which of the two structures you drew in 6 and 7 would be the predominant form of the species at a pH well above that at the equivalence point? b) Which of the two structures would be the predominant form of the species at a very low pH, well below that at the equivalence point and similar to the pH near the start of the titration? c) At what point in the titration, if any, would there be equal amounts of the two forms?
Discuss the justification for this statement: “Although one does not normally regard NH+4 as an acid, it is actually only slightly weaker as an acid than hydrocyanic acid, HCN, in aqueous solution.”
Tartaric acid is found in many fruits, including grapes, and is partially responsible for the dry texture of certain wines.
