What is the stronger base HS or HSO4?
Also, in a series of oxyacids with the same central atom (CI), the acid with more O atoms is stronger (Section 16.10). (b) HS-, H2SO4 is a stronger acid than H2S, so HS- is the stronger conjugate base. In fact, since H2SO4 is one of the seven strong acids, HSO4 is a negligible base.
IS F a strong or weak base?
It is a weak base because F is a most electroneagtive elements which has more affection towards electron and it will never donates electron to other so it is a weak base.
How do you know which base is stronger?
What determines the strength of a base?
- The less electronegative an atom (the later it appears in the periodic table), the more basic it likely is.
- If electron density can be delocalized by resonance, the molecule is a weaker base as it is less interested in losing electrons and accepting a proton.
Is f an acid or base?
| Ka | Acid | Base |
|---|---|---|
| 6.6 * 10-4 | Hydrofluoric acid | F – |
| 1.8 * 10-4 | Methanoic acid | HCO2 – |
| 6.3 * 10-5 | Benzoic acid | C6H5COO- |
| 5.4 * 10-5 | Hydrogen oxalate ion | O2C2O2 2- |
Which is a stronger base HS or HSe?
4.23 Remember the organic method – the strongest acid has the most stable conjugate base. By this definition, HS¯ is less stable than HSe¯ because the latter has a bigger atom and is better able to sustain a negative charge. Thus, HSe¯ is the more stable conjugate base and H2Se is the stronger acid.
Which is the weakest conjugate base?
HCl being the strongest acid (out of these ) and hence, has weakest conjugate base.
Can f act as a base?
The reverse of this reaction represents the hydrolysis of the ammonium ion. Because HF is a weak acid, fluoride salts behave as bases in aqueous solution. As a Lewis base, F– accepts a proton from water, which is transformed into a hydroxide ion.
WHY IS F a good base?
In fluoride, the negative charge is confined to a much smaller volume meaning that positive charges such as a proton are attracted stronger. This is the underlying reason for the observed acidities/basicities.
Is F 1 a strong base?
Since HF is a weak acid, F1- is also a weak base.
