Why is HF a liquid when H2 is a gas?
The principal reason is the hydrogen bonding between HF molecules. The second reason is that London dispersion forces will be higher in HF because it has more electrons than H2
What is the compound name for hydofluoric acid?
Hydrofluoric acid is a solution of hydrogen and fluoride mixed with water. Its chemical formula is HF. It is a chemical compound and considered a weak acid but can be heavily corrosive.
Explain the different between Hf and HF?
Hf is the element hafnium. A dense gray metal. HF is the compound hydrogen fluoride, a toxic, acidic gas.
What formula represent hydrofluoric acid?
Hydrofluoric acid is a water solution of hydrogen fluoride (HF).
Is HF and acid base or salt?
HF is a weak acid.
Why HF less viscous than water?
due to more h-bonding in water as compared to Hf
Why hf is less viscous than h2o?
Due to strong H-bonding in H20 than HF.That is why HF IS LESS VISCOUS
Why hydrogen bond in water is stronger than in HF and NH3?
In HF molecule hydrogen bonding is the strongest. The reason is that the partial positively charged hydrogen atom is entrapped between the two highly electronegative fluorine atoms.
Why HI acid is stronger than HF acid?
Yes, acidity of the hydrides increases down group 17. This is largely because the bond strength of the hydride decreases as we go down the group, making it easier to break the bond and form ions.http://depts.washington.edu/eooptic/links/acidstrength.html
What is H2O in HF?
water in hydrofluoric acid
Which of the following describes an exothermic reaction A. ht reactants equals 0 B. ht reactants ht products C. ht equals ht D. ht ht?
Hf, reactants > Hf, products apex
Why boiling point of H2O is higher then HF?
Both H2O and HF possess H bonds as their intermolecular force but H bonds of HF are stronger than that of H2o. therefore boiling point of than that of H2O. But experimental boiling point is high in H2O than that of Hf
Does HF dissolve in water?
Yes, the hydrofluoric acid is soluble in water.
How does Fluorine react with water?
Fluorine reacts with water to produce Hydrogen Fluoride(HF) and Oxygen(O2).2 H2O + 2 F2 ----> 4 HF + O2
Is hf plus H2O acidic?
Assuming you mean HF (hydrogen fluoride) Oh, YES - it is quite acidic. When HF is dissolved in water it forms hydrofluoric acid - which can etch glass!
Why is hydrogen fluoride a weak acid?
Hydrogen fluoride (HF) is considered a weak acid because it only partially ionizes in water. When HF is dissolved in water, it undergoes a partial dissociation into hydrogen ions (H⁺) and fluoride ions (F⁻). The equilibrium reaction for this process can be represented as follows: HF ( � � ) ⇌ H ( � � ) F − ( � � ) HF(aq)⇌H (aq)+F − (aq) In this equation, the double arrow indicates that the reaction is reversible, and not all HF molecules dissociate into ions. The majority of HF molecules remain in molecular form. The reason for the partial dissociation of HF lies in the strength of the bond between hydrogen and fluoride in the HF molecule. The hydrogen-fluorine bond is a strong covalent bond, and it is not easily broken. As a result, only a small fraction of HF molecules dissociate into ions when dissolved in water, making HF a weak acid. In contrast, strong acids, such as hydrochloric acid (HCl) or sulfuric acid (H₂SO₄), completely ionize in water, producing a high concentration of hydrogen ions. The strength of an acid is related to the extent of ionization in water, and weak acids ionize only partially.
What is true about a solution of 1.0 M HF?
HF has a higher [OH-] than a solution of 1.0 M HCl.
