Sodium acetate (NaBr), a salt, is a compound of sodium and bromide. The bromide ion (Br-) forms when hydrobromic acid (HBr), a strong acid, loses a hydrogen ion (H+). When sodium acetate is dissolved in water, it dissociates into sodium ions (Na+) and acetate ions (CH3COO-). The dissociation of sodium acetate does not produce hydrogen ions or hydroxide ions (OH-), so it does not affect the pH of the solution.
Is NaBr an Acid or Base?
Sodium bromide (NaBr) is a neutral salt composed of sodium and bromine ions. When dissolved in water, it does not undergo hydrolysis to a significant extent, and thus does not exhibit acidic or basic properties in aqueous solutions. Here’s a closer look at the reasons why:
-
Weak Acid and Base Components: NaBr is formed from a strong base (NaOH) and a strong acid (HBr). When these components react, they neutralize each other, resulting in a neutral salt.
-
Lack of Ionization in Water: When NaBr dissolves in water, it dissociates into sodium (Na+) and bromide (Br-) ions. However, these ions do not undergo any further ionization or hydrolysis to produce H+ or OH- ions in significant amounts.
-
pH of NaBr Solution: The pH of a 0.1 M solution of NaBr is approximately neutral (around 7), indicating the absence of significant acidic or basic properties.
-
Conductivity of NaBr Solution: The electrical conductivity of a NaBr solution is relatively low, which is characteristic of neutral solutions. Highly acidic or basic solutions usually exhibit higher conductivity due to the presence of free H+ or OH- ions.
In summary, NaBr is a neutral salt that does not exhibit appreciable acidic or basic properties in aqueous solutions because:
- It is formed from strong acid and base components that neutralize each other.
- Its ions do not undergo significant hydrolysis or ionization in water.
- It has a neutral pH and low electrical conductivity, indicating the absence of significant acidic or basic behavior.
Question 1:
Is NaBr acidic or basic in nature?
Answer:
Sodium bromide (NaBr) is a salt that, in aqueous solution, dissociates into sodium ions (Na+) and bromide ions (Br-). Bromide ions are the conjugate base of the weak acid hydrobromic acid (HBr). Therefore, in water, NaBr acts as a weak base.
Question 2:
What is the pH of a solution with a high concentration of NaBr?
Answer:
A solution with a high concentration of NaBr will have a pH greater than 7. This is because the hydrolysis of bromide ions in water produces hydroxide ions (OH-), increasing the concentration of OH- ions and thus increasing the pH.
Question 3:
How does the concentration of NaBr affect its acid-base properties?
Answer:
The concentration of NaBr affects its acid-base properties because it affects the extent of hydrolysis. At low concentrations, the hydrolysis of bromide ions is negligible, and NaBr behaves as a neutral salt. However, at high concentrations, the hydrolysis of bromide ions becomes significant, resulting in the formation of hydroxide ions and a basic solution.
