is C8H7O2COONa an acidic salt or basic salt?
basic because the C8H7O2 is a weak acid, and Na is part of a strong base.
To determine whether C8H7O2COONa is an acidic or basic salt, we need to consider the nature of the individual components.
C8H7O2COOH is a weak acid, commonly known as benzoic acid. Weak acids partially dissociate in water, so they do not release all of their hydrogen ions. As a result, the solution of C8H7O2COOH in water will be slightly acidic.
Na, on the other hand, is part of a strong base (NaOH). Strong bases fully dissociate in water, releasing hydroxide ions (OH-) and increasing the pH, making the solution basic.
When a weak acid reacts with a strong base, a neutralization reaction occurs and the resulting salt is generally neutral. However, it is important to note that the salt may have acidic or basic properties depending on the relative strengths of the acid and base.
In this case, since benzoic acid (C8H7O2COOH) is a weak acid and Na is part of a strong base (NaOH), the salt C8H7O2COONa is considered a basic salt. This is because the basic nature of the NaOH component outweighs the weak acidity of the benzoic acid component, resulting in an overall basic salt.
To determine whether C8H7O2COONa is an acidic or basic salt, we need to analyze the properties of its components.
The C8H7O2 group is derived from an organic acid called benzoic acid (C6H5COOH). Benzoic acid is a weak acid, which means it partially dissociates in water, releasing H+ ions.
On the other hand, Na is a sodium ion derived from sodium hydroxide (NaOH), which is a strong base. Sodium hydroxide fully dissociates in water, producing Na+ ions and OH- ions.
When we combine benzoic acid and sodium hydroxide, the acid-base reaction occurs, resulting in the formation of C8H7O2COONa. As a result, C8H7O2COONa contains the conjugate base of benzoic acid (C8H7O2-) and the sodium ion (Na+).
Since C8H7O2- is the conjugate base of a weak acid and Na+ is derived from a strong base, the resulting salt C8H7O2COONa is considered a basic salt. It will have basic properties when dissolved in water.
