Which experiment best shows water’s ability to act as a solvent? raise the temperature of water and record its boiling point. freeze a flexible vessel of water and watch it expand. pour an ionic solid into water and see if it vanishes. place a leaf on top of the surface of water and see if it sinks?

pour an ionic solid into water and see if it vanishes.

Explanation: The solubility of substances is governed by: Like dissolves like, which states that polar compounds are soluble in polar solvents and non polar compounds are soluble in non polar solvents.

Ionic compounds are formed by combination of positively charged cations and negatively charged anions which are held by strong coloumbic forces.When ionic compounds are dissolved in water, the ions are dissociated due to high dielectric constant of water and thus dissolve in water.

Water being a polar solvent is able to dissolve ionic or polar compounds in it.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
