Answer:
chemical change
Explanation:
A physical change is one that makes changes to the physical properties of matter. In many cases, the difference is usually reversible. Examples include boiling, melting, freezing, the magnetization of metals, etc.
A chemical change is one in which a new kind of matter is formed. It is usually accompanied by energy changes, i.e., the evolution or absorption of energy in the form of heat or light. This process is not easily reversible. Examples include; combustion, rusting of iron, precipitation, the souring of milk, etc.
From the question given, the combination of two clear liquid in a beaker which results to formation of bubbles and changes in coloration of the solution is a chemical change.
Chemical process is responsible for the smell of vinegar in an old bottle of aspirin is Hydrolysis of ester i.e. Aspirin.
Aspirin reacts with water leading to the formation of Acetic acid which is a Carboxylic acid derivative.
Aspirin on Hydrolysis forms Acetic acid and Salicylic acid.
The reaction shows up as a fizz when aspirin is added in water.
Aspirin is called Acetyl Salicylic acid and it helps to reduce:
- Inflammation
- Pain
- Fever
- Headache
- Arthritis
- Muscle pain
- Tooth pain
Acetic acid or Ethanoic acid is a colorless liquid. It is an important carboxylic acid. It smells like vinegar.
Acetic acid is used for production of following:
- Vinyl Acetate
- Insecticides
- Rubber
- Acetic anhydride
Salicylic acid is a bitter compound which is colorless. It reduces acne and opens up the skin pores.
