Which acid has the weakest conjugate base?
HClHCl,A strong acid gives a weak base. HCl being the strongest acid (out of these ) and hence, has weakest conjugate base.
What generates the weakest conjugate acid?
⚛ The weaker the acid, the stronger its conjugate base. ⚛ The stronger the base, the weaker its conjugate acid.
Which of the following will have the weakest conjugate base?
- A strongest acid will give a weakest conjugate base.
- In this example of HF,H2O, H-COOH and HCN ,the pKa Values are 3.14, 14.0, 3.75, 9.21 respectively.
- So HF, is the strongest acid among the given acids.
- HF———>H+ + F-.
- The H+ ion removed part of the acid is called the conjugate base.
What is the weakest weak acid?
The chloride ion is incapable of accepting the H+ ion and becoming HCl again. In general, the stronger the acid, the weaker its conjugate base. Likewise, the weaker the acid, the stronger its conjugate base….Strong and Weak Acids and Acid Ionization Constant.
| Acid | Conjugate Base |
|---|---|
| HCN (hydrocyanic acid) (weakest) | CN− (cyanide ion) (strongest) |
What is the strongest Bronsted acid?
carborane acid H
The structure of the strongest Brønsted acid: the carborane acid H(CHB11Cl11)
What is the strongest acid on earth?
Fluoroantimonic acid
Fluoroantimonic acid is the strongest super-acid known in existence. It is 20 quintillion times more acidic than 100% sulfuric acid, and it can dissolve glass plus a host of other substances.
Is oh a base or acid?
OH – is called a hydroxyl ion and it makes things basic. However, in water, there is a balance between hydroniums and hydroxyls so they cancel each others’ charges. Pure water is neither acidic or basic; it is neutral. So how does something become acidic or basic?
Which is strongest conjugate acid?
-Hence CH3COO− will be the strongest conjugate base because it has been formed from the weakest acid (CH3COOH). Note: The concept of conjugate acids and bases belongs to the Bronsted-Lowry theory of acids and bases.
Which has strongest conjugate acid?
H3PO4 is a triprotic acid (i.e. an acid . having three hydrogen ions to donate to bases in an acid-base reaction) and its final conjugate base is PO43-. The acid with the smallest Ka value and therefore the weakest is phosphoric acid, H3PO4. Therefore, it has the strongest conjugate base as a result.
Which is the strongest conjugate base?
CH3COOH is the weakest acid,hence it’s conjugate base is strongest.
Which is a weak base or a strong conjugate?
The conjugate base of a strong acid is a weak base. Moderately Weak Acid – Moderately Weak Conjugate Base Pair A moderately weak Brønsted-Lowry acid has only a slight tendency to donate a proton.
Which is a strong acid-weak base pair?
Strong Acid – Weak Conjugate Base Pair A strong Brønsted-Lowry acid is one which has strong tendency to donate a proton 3 : Strong acids include H 3 O +, HCl and HNO 3. For example, in water, a strong acid like hydrochloric acid readily donates a proton to a water molecule:
Which is a weak base in aqueous solution?
So Cl – must be a weak base, it has very little tendency to accept a proton. The conjugate base of a strong acid is a weak base. A moderately weak Brønsted-Lowry acid has only a slight tendency to donate a proton. For example, acetic acid (ethanoic acid) is a moderately weak acid in aqueous solution .
Which is the weak conjugate base of srtong acid?
The conjugate base of a srtong acid is weak conjugate base. As example ; HCl (g) + H2O = H3O+ (aq) + Cl- (aq) HEre HCl is strong acid and Cl- is wek conjugate base . In any electrochemical cell, reduction occurs at the cathode.
