What is conjugate acid and base with example?
What is conjugate acid and base with example?
An example is the base ammonia, NH3 and its conjugate acid, the ammonium ion, NH4+. The conjugate base, without the extra proton as the base is in a state to accept a proton. Using the example above, that is ammonia, NH3. The conjugate acid, with the extra proton as it can donate that proton to another species.
How do you identify acids and bases?
To determine whether a substance is an acid or a base, count the hydrogens on each substance before and after the reaction. If the number of hydrogens has decreased that substance is the acid (donates hydrogen ions). If the number of hydrogens has increased that substance is the base (accepts hydrogen ions).
What are the conjugate bases of these acids?
An acid and a base which differ only by the presence or absence of a proton are called a conjugate acid-base pair. Thus NH3 is called the conjugate base of NH4+, and NH4+ is the conjugate acid of NH3. Similarly, HF is the conjugate acid of F–, and F– the conjugate base of HF.
What is the conjugate of HCl?
Table of acids and their conjugate bases
| Acid | Conjugate base |
|---|---|
| HCl Hydrochloric acid | Cl− Chloride ion |
| H2SO4 Sulfuric acid | HSO − 4 Hydrogen sulfate ion |
| HNO3 Nitric acid | NO − 3 Nitrate ion |
| H3O+ Hydronium ion | H2O Water |
What is the conjugate base for NH4+?
NH3 OH
NH4+ is the conjugate acid of NH3. OH- is the conjugate base of H2O.
What is the conjugate base of HCl?
Chloride ion
Chloride ion is the conjugate base of hydrochloric acid.
What makes a good conjugate base?
There is a relationship between the strength of an acid (or base) and the strength of its conjugate base (or conjugate acid): ⚛ The weaker the acid, the stronger its conjugate base. ⚛ The stronger the base, the weaker its conjugate acid. ⚛ The weaker the base, the stronger its conjugate acid.
What are the common acids and bases?
| Stong Acids | Strong Bases | |
|---|---|---|
| Hydroiodic acid | HI | Lithium hydroxide |
| Nitric acid | HNO3 | Potassium hydroxide |
| Perchloric acid | HClO4 | Sodium hydroxide |
| Sulfuric acid | H2SO4 | Strontium hydroxide |
What is conjugate acid of NaOH?
The conjugate acid of NaOH is H2O i.e water . Sodium is a spectator ion in the compound NaOH, which means it can be ignored , now when a base accepts a proton, it forms a conjugate acid , so in the solution OH- ion accept a proton i.e. H+ to form H20.
