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...
In the reaction shown below, HCl is the acid because it donates an H+, and H2O is the base because it accepts an H+ to form H3O+. HCl(aq)+H2O→H3O+(aq)+Cl−(aq) Similarly, if we react sodium hydroxide (NaOH) with hydrochloric acid we end up with the following reaction. NaOH...
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. ...
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...
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...
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 ...
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. ...
a teacher is good at chemistry, this is no indication of their ability to teach you or your child. The dissociated molecules are in equilibrium with undissociated molecules. No matter how much water you remove, that will be true. What happens when you mix a strong acid and a strong base...

The terminology used for leaders following the previously established plasma channel is unfortunately somewhat inconsistent. The leaders occurring within CG flashes below the cloud base are called dart or dart-stepped leaders (Biagi et al., 2010; Dwyer & Uman, 2014; Petersen & Beasley, 2013; ...
