9.2: Acid–Base Titrations - Chemistry LibreTexts

WebThe graph indicates that the acid being titrated has a pKa value between 4 and 6, making it a weak acid. This eliminates possibilities like hydrogen gas (Hd), which isn't an acid, and acids with pKa values that are noticeably higher or lower than this range. Therefore, based on the available alternatives, option 6, a weak acid with a pKa value ...

WebHydrogencarbonate, auch saure Carbonate oder veraltet Bicarbonate, sind die Salze der Kohlensäure, die durch einfache Neutralisation dieser Säure mit einer Base entstehen. Oft … WebThe sample is titrated against hydrochloric acid using phenolphthalein and methyl orange as indicators; the absorbance is measured at 430nm. A logarithmic relationship is obtained … WebBecause hydrogen carbonate ion is a weak base, the equivalence point in this titration will be well on the acid side at around pH 5. Consequently, an indicator like methyl orange, which changes color around that pH, is used to indicate the equivalence point. aerolinea boliviana de aviacion
