Is Cl A strong or weak acid?
Strong acids have a weak conjugate base.

| Strong acid | Weak base |
Is chloride a strong or weak base?
Keep in mind that a salt will only be basic if it contains the conjugate base of a weak acid. Sodium chloride, for instance, contains chloride (Cl–), which is the conjugate base of HCl. But because HCl is a strong acid, the Cl– ion is not basic in solution, and it isn’t capable of deprotonating water.
How strong is CL as a base?
Cl- has little tendency to gain a proton so it is a weak base, but its conjugate acid, HCl, has an enormous tendency to donate a proton it is a strong acid. The conjugate acid of a weak base is a strong acid. Footnotes: 1.
Is HNO2 a weak acid?
Nitrous acid (HNO2), a weak acid, is very unstable and exists only in aqueous solution.
Is HNO2 strong or weak?
Which is a strong base HCl or Cl?
A very weak acid always forms a strong conjugate base. A very weak base always forms a strong conjugate acid. So, HCl is a strong acid which forms a weak conjugate base. The conjugate base of HCl is Cl–.
Which is the weakest acid in the world?
The strong acids are hydrochloric acid, nitric acid, sulfuric acid, hydrobromic acid, hydroiodic acid, perchloric acid, and chloric acid. The only weak acid formed by the reaction between hydrogen and a halogen is hydrofluoric acid (HF). While technically a weak acid, hydrofluoric acid is extremely powerful and highly corrosive.
What makes a ligand a strong or weak ligand?
Being lewis bases (those who donate electrons) the ligands with less electronegativity will be stronger. Therefore, in general halogen or oxygen donors (eg-F-,Cl-,Br-,H2O) are weak field ligands and the ones in which carbon or nitrogen atom is the donor (eg-CN-,CO,NH3) are strong field ligands.
How can you tell if an acid is a strong or weak acid?
Distinguishing Between Strong and Weak Acids. You can use the acid equilibrium constant K a or else pKa to determine whether an acid is strong or weak. Strong acids have high K a or small pK a values, while weak acids have very small K a values or large pK a values.
