Sand is not soluble in any water. It can be suspended in water, but never dissolved.
Sand will not dissolve in water.

Potassium hydrogen carbonate is soluble in water.
permeable
Filter the sand, salt, water mixture to remove the sand. Then boil the salty water to produce steam (water vapour). Then condense the steam onto a cold surface, fresh water droplets will form on the cold surface. If the steam is captured in a condenser, the steam will return to fresh water.
It is soluble but does take a little effort to get it into solution.
souble means that it can dissolve into another substance
Warm water can dissolve more easily several possible impurities from the sand.
Sand, or silicon oxide, is fairly inert. It does not dissolve in water. Sand is mostly the same material as glass. So it does not dissolve any faster than glass dissolves in cold water. Hydrofluoric acid is, however, another matter.
Wet sand has more moisture content, which helps to conduct heat away from the body more effectively than dry sand. This removes heat from your feet, making it feel cooler to walk on compared to dry sand, which does not conduct heat as effectively.
Sand heats up faster than water when exposed to sunlight due to its lower specific heat capacity. This means it absorbs heat quickly and feels hot to the touch. In contrast, water has a higher specific heat capacity, so it retains its temperature better and feels cooler compared to the sand on a hot day.
