Answer:
A. Acidic
B. Neutral
C. Basic
D. Acidic
E. Basic
Explanation:
The reaction of salts with water to give aqueous solutions which are either acidic, basic or neutral is known as salt hydrolysis. Salts that are produced from the reaction of strong acids and weak bases give acidic solutions. Salts that are produced the reaction between weak acids and strong bases give basic solutions. Neutral solutions are obtained from salts produced bynthe reaction of strong acids and strong bases.
The hydrolysis of the given salts are shown below:
A. AlCl₃ + 3 H₂O ---> 3 HCl + Al(OH)₃
The aqueous solution produced will be acidic since HCl is a strong acid while Al(OH)₃ is a weak base.
B. NaBr + H₂O ----> HBr + NaOH
The aqueous solution produced will be neutral since HBr is a strong acid and NaOH is strong base as well.
C. NaClO + H₂O ----> HClO + NaOH
The aqueous solution produced will be basic since HClO is a weak acid while NaOH is a strong base.
D. CH₃NH₃NO₃ + H₂O ----> HNO₃ + CH₃NH₂ + H₂O
The aqueous solution produced will be acidic since HNO₃ is a strong acid while CH₃NH₂ is a weak base.
E. Na₂SO₃ + 2 H₂O ----> H₂SO₃ + 2 NaOH
The aqueous solution produced will be basic since H₂SO₃ is a weak acid while NaOH is a strong base.
Based on the products formed when they react with water, the following is true:
- AlCl₃ - Acidic.
- NaBr - Neutral.
- NaClO - Acidic.
- 3CH₃NH₃NO₃ - Acidic.
- Na₂SO₃ - Basic.
What happens when the above compounds react with water?
When AlCl₃ reacts with water, it produces Hydrochloric acid which is a strong acid. The solution will be acidic.
NaBr reacting with water produces a strong base in Sodium Hydroxide and a strong acid in Hydrobromic acid. As they are both strong, they will cancel the other out and leave a neutral solution.
NaClO will produce a weak acid and a strong base which is Sodium Hydroxide. Solution will be basic.
3CH₃NH₃NO₃ will produce a weak base and a strong acid - Nitric Acid - which would make the solution acidic.
Na₂SO₃ would produce the strong base Sodium Hydroxide and a weak acid so the solution will be basic.
