WebAfter completing the two-week experiment, what would be the most likely identity of your acid if you find a pKa of 4.84 and a molar mass of 73.9 ... Note that in cases where your experimentally determined molar mass and pK a values suggest different weak acid identities, the molar mass is usually the more reliable indicator. Table I. Possible ... WebA typical example of an Arrhenius acid is something like hydrochloric acid (HCl). While a typical example of an Arrhenius base is something like sodium hydroxide (NaOH). Once those species dissociate, HCl gives H + into the solution, while NaOH gives off the OH – ion.
WebAug 14, 2024 · 50.00mL(0.100mmolHCl mL) = 5.00 mmol HCl = 5.00 mmol H + The number of millimoles of NaOH added is as follows: 24.90mL(0.200mmolNaOH mL) = 4.98 mmol NaOH = 4.98 mmol OH − Thus H + is in excess. To completely neutralize the acid requires the addition of 5.00 mmol of OH − to the HCl solution. WebpKa. Chemical Formula. Name –10. HClO 4. Perchloric acid –7. HCl. Hydrochloric acid –3.0.
