Why is HF a weak acid? Hydrofluoric acid (HF) is a weak acid mainlybecause it forms stable species after it dissociates. ... This makes HF the only hydrohalic acid that isn't classified as a strong acid (e.g., HCl, HBr, HI). What type of reaction is HF? Hydrogen fluoride is p...
Which one of the following is a weak acid? a. H2SO4 b. HI c. HBr d. HF e. HClO4 Acid Strength: Acids can be strong, in which they fully dissociate in water to make the same concentration of hydronium ions as the concentration of acid, or they can be weak an...
If a 7.88 \times 10^{-4} solution of a weak acid is 18.8% ionized, what is the pK_a for the acid? Which of the following acids is the stronger, (a) boric acid, pKa = 9.0, or (b) acetic acid, pKa = 4.6? R...
Which of the acids below will have the lowest pH in a 0.10 M solution of the acid? a. HClO b. HNO2 c. HSO4- d. HCO3- Is H2CO3 classified as a strong or a weak acid? Explain. Which of the following is a salt that will form from the combination o...
Supplying water in the form of a spray or fog (rather than a stream) on the fume cloud or downwind of the source can help reduce acid and vapor. As noted above, the water supply will create runoff containing weak acid solutions, so it ...
Hydrogen bromide is also a strong acid and is corrosive. 16.碘化氢是一种弱酸,但同样具有刺激性。 Hydrogen iodide is a weak acid but still has an irritating nature. 17.氢氟化物的沸点较低,易在室温下挥发。 Due to its low boiling point, hydrogen fluoride easily vaporizes at room temperature. ...
By incorporating a weak base, such as a sulfide or mercaptan, to serve as a solvent for the HF, the acidity function of the HF is lowered to an Ho between -4.6 and -5.2 (14). This acid strength is strong enough to protonate most of the weak base protecting groups, such as benzyl ...
A buffer solution is described as an aqueous solution composed of a weak base and its conjugate acid, or vice versa. This is used to maintain the pH range of a solution upon the addition of small amounts of acid or...
A buffer solution can also be prepared using weak acid and strong base. The weak acid reacts with hydroxide ions to form the conjugate base: $$HF+OH^...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a questi...
Is HF classified as a strong acid, weak acid, strong base, or weak base? Explain.What occurs when HF dissociates in water as compared to the other hydrogen halides?A 8.6 x 10^(-3) M solution of H3PO4 has a pH = 2.30. What is Ka for H3PO4?Which one of the following is not...
