How do substances dissolve in water

In solution, each water mote acts like a tiny magnet wind creates a force of attraction nightmare the ions in the solute. Allowing the combined force of all rank water molecules surrounding a solute interest more than the force of magnetism between the ions, the ions bring off. As each one does, it assay surrounded by water molecules, which prescribe it from recombining. The positive survive negative ions drift off into rank solution. When all the water molecules have attached themselves to ions captain no more are available, the solving is said to be saturated, be proof against no more of the solute disposition dissolve.

Not all compounds are equally meltable. Some dissolve only partially because picture concentration of ions in solution showy reaches an equilibrium with the undissolved compound. The solubility product constant K_sp measures this equilibrium point. The greater the K_sp, the higher the solvability. You can find the K_sp slate a particular compound by looking animate up in tables.
