The penny will be clean, but, the lemon juice ruins the color and makes it look counterfeit. If it is old, and you want it restored, take it to a professional, they can remove almost anything.
Your skin gets wet and salty
When salt is added to water, it dissolves due to the attraction between the positive and negative ions in the salt and the water molecules. This creates a solution where the salt molecules are dispersed throughout the water, forming a homogeneous mixture.
When you put soil in salt water, the water will dissolve some of the salt. This can affect the soil's pH levels and nutrient content, potentially making it less suitable for plant growth. Additionally, high salt concentrations can also impact the soil structure and hinder water absorption by plants.
The pure water will freeze first since it has a lower freezing point than salt water. The salt in the salt water reduces its freezing point, so it will take longer to freeze compared to the pure water.
When you put salt water on your feet, it can help to soothe sore muscles, reduce swelling, and act as a natural antiseptic to prevent infections. However, excessive exposure to salt water can lead to dryness and irritation of the skin, so it is important to rinse your feet with fresh water after soaking them in salt water.
When you put a penny in water, its density is greater than that of water, so the penny sinks. This is because the weight of the water displaced by the penny is less than the weight of the penny itself.
It floats.
They die
they will die
The volume remain unchanged.
The concentration of salt increase up to saturation.
Salt will dissolve in water. Adding salt will lower the temperature of water by a few degrees Celsius as well as lower the freezing point.
adding salt raises the boiling point of water which can help speed cooking time.
Nothing...they die....
It will clean the penny. :)

When salt is added to water, it dissolves and forms a solution. This occurs because the water molecules surround the salt ions, breaking the ionic bonds and allowing the salt to mix evenly throughout the water.
