WebJun 21, 2012 · 11 No, it can’t be generalised. Amongst the haloacids, only H F is weak. Acid strength can be determined by the stability of the conjugate base (for most acids, the conjugate base is what you get when you remove H X + from the acid). In this case the conjugate bases are the halides. WebHNO2 Ka = 4.5 10-4 HF Ka = 6.8 10-4 Need to find weakest acid, therefore its conjugate base will be the strongest. Weakest Acid is one with smallest Ka, which is HOAc Therefore strongest conjugate base is OAc- (a) Ans. Need to find strongest acid, therefore its conjugate base will be the weakest.

WebDec 1, 2024 · Hydrofluoric acid is a much stronger acid when it is concentrated than when it is diluted. As the concentration of hydrofluoric acid approaches 100 percent, it's acidity …
WebMay 3, 2013 · Hydrofluoric acid is toxic and corrosive, but actually isn't that strong of an acid compared to other hydrohalic acids; the fluorine has a very good orbital overlap with hydrogen and is also not very polarizable, therefore it resists donating its proton, unlike other hydrohalic acids which are good proton donators. WebDec 30, 2024 · KOH is a base. Because when it is dissolved in an aqueous solution, it gives two ions K + and OH –. And any molecule which gives OH – in a water solution is defined as a base in nature. Its pH value lies between 12-13. KOH is generally less preferred for industrial uses because of its high-cost issue. Name of Molecule.
Web1 day ago · Here, since F-ion is the conjugate base, and it is very unstable, the HF molecule will prefer to stay in its un-ionized form. Further, since the fluorine atom is very small, its bond with hydrogen is a very strong bond. 1s orbital of hydrogen and 2p orbital of fluorine share electrons to form the HF molecule.
