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 and how will each bottle smell if the experiment is left to stand for one day?
1. The bottle with salt added to it will not undergo any chemical reaction. It will still be water, but it may taste slightly salty.
2. The bottle with HCl added to it will undergo a chemical reaction that produces chloride ions and hydrogen gas. The hydrogen gas may produce a slightly sour smell. The resulting solution may be highly acidic and may burn or irritate the skin if touched.
3. The bottle with calcium hydroxide added to it will undergo a chemical reaction that produces calcium ions and hydroxide ions. The resulting solution is likely to be highly basic and may feel slippery or soapy to the touch. It may have a strong ammonia-like smell.
4. The bottle with vinegar added to it will undergo a weak acid-base reaction with the water. The resulting solution will still be acidic, but not as strongly acidic as the bottle with HCl. It may have a sour or vinegary smell.
5. The bottle with baking soda added to it will undergo a weak base-acid reaction with the water. The resulting solution will still be basic, but not as strongly basic as the bottle with calcium hydroxide. It may have a slightly soapy smell.
6. The bottle of water left alone will not undergo any chemical reaction. It will still be water and will not have any particular smell.
1. The bottle with salt added: The salt will dissolve in the water, and the water will still smell like water. There won't be any significant change in smell.
2. The bottle with HCl: HCl is a strong acid, so it will react with the water to form hydrochloric acid (HCl) solution. The solution will have a strong, pungent smell similar to that of vinegar.
3. The bottle with calcium hydroxide: Calcium hydroxide is a strong base, and it will react with water to form calcium hydroxide solution. The solution will have a slightly alkaline smell or odor.
4. The bottle with vinegar: Vinegar is a weak acid, and it will mix with water to form acetic acid solution. The solution will retain the sour, vinegar-like smell.
5. The bottle with baking soda: Baking soda is a weak base, and it will react with water to form a solution of sodium bicarbonate. The solution will have a slightly alkaline smell similar to that of calcium hydroxide.
6. The bottle left unchanged: This bottle will remain the same without any added substances, so it will only have the smell of plain water.
