Final answer:
The solubility and maximum concentration of a solution depend on factors such as the nature of the solute and solvent, temperature, and pressure, not solely on stirring intensity, making the statement false.
Step-by-step explanation:
The statement that the solubility of a solid in a liquid and the maximum concentration of a solution is dependent only on the intensity of stirring is false. Solubility is the maximum concentration of a solute that may be achieved under given conditions when the dissolution process reaches equilibrium. Factors such as temperature and pressure significantly influence solubility. For instance, solubilities for gaseous solutes decrease with increasing temperature, while those for most solid solutes typically increase. Moreover, a saturated solution contains a solute at a concentration equal to its solubility; if the concentration exceeds this solubility, it results in a supersaturated and unstable solution that leads to solute precipitation on perturbation. The identity of the solute and solvent, their interactions, and the temperature are key determinants of solubility, not just mechanical stirring.
