If the hydrocarbon stream further includes a nitrogen-containing compound such as ammonia, a tramp and/or a residual amine which can form a corrosive salt with the mineral acid, then the added amine is a stronger base than the tramp or residual amine, if present. The amount of added amine...
Example Problem 1 - How to Perform a Titration of Excess Weak Acid with a Strong Base A 0.75 M acetic acid (pKa = 4.75) solution has a volume of 100 mL. If 50 mL of 0.6 M NaOH is added to the solution, identify the pH of the solution at equilibrium. ...
So, a Bronsted-Lowry acid is a substance (ion or molecule) that donates (gives up) a hydrogen ion to another substance. A Bronsted-Lowry base is a substance that accepts a proton from another substance. To better understand these definitions, we will take a closer look at the dissociation...
201 "Henderson-Hasselbalch” equations: if working with Ka, if working with Kb, at the first e.p. of a diprotic acid, [A] [BH] pH =pKa + logo pOH =pKb + log. pH = (pKai+pka2) [HAI [B] where A is the conjugate base wh...
Why would it be before equivalence point if the amount of weak acid was greater than the amount of strong base? Why is phenolphthalein an appropriate indicator for a weak acid-strong base titration? Explain the titration curve of a strong acid vs. a strong base ...
Classify the compound given as a strong acid, weak acid, strong base, or weak base. CsOH An acid with a low pKa: A. is a weak acid B. is a strong acid C. has a weak conjugate base D. both B and C When a strong acid reacts with a weak base, the resulting solution wil...

Atomic radius: As the atomic radius increases, so does acidity. For example, HI is a stronger acid than HCl (iodine is a larger atom than chlorine). Electronegativity: The more electronegative a conjugate base in the same period of the periodic table is (A-), the more acidic it is. ...
3. Interpret the Comparison: - Since pKa(A) is greater than pKa(B), it implies that: Ka(A)<Ka(B) - This means that acid A has a lower tendency to dissociate compared to acid B.4. Determine Which Acid is Stronger: - Since a stronger acid has a higher Ka ...
