There are 6 bottles of water. Salt is added to the first one, a strong acid namely HCl to the 2nd one, a strong base namely calcium hydroxide to the 3rd one, a weak acid namely vinegar to the 4th one, a weak base namely baking soda to the 5th one and the 6th bottle of water is left in the same way.
What will happen to each bottle, what will each bottle look like and how will each bottle smell if we look at the experiment for the third day?
Assuming the experiment is carried out under normal conditions (room temperature, atmospheric pressure, etc.), here's what is likely to happen to each bottle after three days:
1. The bottle with salt added: The water will become slightly cloudy due to the salt dissolving in it. However, there will not be any significant change in the appearance or smell of the water.
2. The bottle with HCl added: HCl is a strong acid that can react with water to form hydronium ions (H3O+). This will make the water highly acidic and corrosive. The bottle will release fumes that smell like vinegar, and the water will be cloudy and might even have a yellowish tint.
3. The bottle with calcium hydroxide added: Calcium hydroxide is a strong base that can react with water to form hydroxide ions (OH-). This will make the water highly alkaline and caustic. The water will look cloudy and might have a milky appearance. It will also have a bitter taste and a strong odor, similar to bleach.
4. The bottle with vinegar added: Vinegar is a weak acid that will not significantly alter the pH of water. However, the acetic acid in vinegar can react with other compounds in the water, producing a variety of byproducts, including carbon dioxide and other organic acids. The water might appear slightly cloudy and will have a distinct odor of vinegar.
5. The bottle with baking soda added: Baking soda is a weak base that will slightly increase the pH of water. However, it can also react with other compounds in the water, producing carbon dioxide gas. This will make the water look fizzy and might even cause the bottle to overflow. The water will have a slight alkaline taste and a subtle odor of ammonia.
6. The bottle left as is: Since nothing has been added to this bottle, the water will remain unchanged after three days. It will look clear and odorless.
