Pka etanol
WebpKa stays the same, but pH is now changed due to change in ratio of conjugate base/acid. pH = 6.2 + log (0.02mol/0.08mol) = 6.2 + (-.60) = 5.60 , So the new pH is 5.60 A compound has a pKa of 7.4. Initially you had 100 mL of a 1.0 M solution of this compound at pH 8.0 But later you decide to add 30 mL of 1.0 M hydrochloric acid. WebThe first thing we would need to do is to find the acid and the conjugate acid. Then we’ll find the pKa values for those. We know that acid loses the proton in an acid-base reaction, …

EtOH; also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound. It is an alcohol with the chemical formula C2H6O. Its formula can also be written as CH3−CH2−OH or C2H5OH (an ethyl group linked to a hydroxyl group). Ethanol is a volatile, flammable, colorless liquid with a characteristic wine-like odor and pungent taste. It is a psychoactive recreational drug, and the active ingredient in alcoholic drinks.
