1) The bottle with salt added will likely not have any significant changes in its smell or appearance, but it may taste slightly different due to the salt content.
2) The bottle with HCl added will likely have a strong acidic smell and may also have a cloudy appearance due to the reaction between the acid and water. Over time, the acid may continue to react with the water and potentially corrode the bottle.
3) The bottle with calcium hydroxide added will likely have a slightly bitter smell due to the presence of the base. It may also have a cloudy appearance initially, but over time, the calcium hydroxide will likely settle at the bottom of the bottle.
4) The bottle with vinegar added will likely have a strong acidic smell similar to that of the HCl bottle. However, the weak acid in vinegar will not react as strongly with the water as the HCl and may not result in any significant changes in appearance.
5) The bottle with baking soda added will likely have a slightly alkaline or soapy smell due to the presence of the weak base. It may also initially have a fizzy appearance as the baking soda reacts with the water, but this should settle over time.
6) The control bottle left untouched will likely not have any significant changes in smell or appearance.
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 per day and how will each one smell per day if the experiment is left like this for a week of 7 days?
