heat or stir
No
usually heat the liquid
You could crush the solid, stir the solution, and/or heat the solution.
If the solid is soluble (can dissolve) then it will dissolve in the liquid and give you a solution.
liquid
When a solid does not dissolve into a liquid, it is referred to as insoluble. This means that the solid remains in its original form and does not mix evenly with the liquid.
If you combine a solid and a liquid, the solid may dissolve into the liquid to form a solution, or it may remain as separate phases. The solid could also partially dissolve in the liquid, forming a suspension. The outcome will depend on the specific properties of the solid and liquid being combined.
The liquid is called a solvent. It has the ability to dissolve solid particles, forming a solution.
When you wish to dissolve a solid in a liquid faster, you increase the temperature. This makes the solid particles move faster and farther, and thus dissolve in the liquid faster. However, the problem with dissolving a gas is the opposite: gas particles already are moving fast and far, to the point where it is difficult to keep them stay in the liquid. The opposite is thus done, lower the temperature. A good example is a can of soda. Cold soda is almost always fizzier than warm soda because the carbon dioxide is dissolved more in the liquid. cool the liquid and increase the pressure
it depends on the solubility of the solid in that specific liquid. If the solid is highly soluble, then it should dissolve completely forming a solution, possibly coloured. If it is not, then it will just sit in the liquid.
No, not all solids dissolve in all liquids. The ability of a solid to dissolve in a liquid depends on various factors such as the nature of the solid and the liquid, as well as their molecular structures. Some solids may dissolve in one liquid but not in another.
If you try to dissolve a lot of solid in a small amount of liquid, you may reach a point where the liquid becomes saturated and can no longer dissolve any more of the solid. The excess solid will remain undissolved at the bottom of the container.
