A solution of ethanol in water is an example of:
Ideal solution
Non-ideal solution
Concentrated solution
Saturated solution
Ethanol and water form an ideal solution because they show a negative deviation from Raoult's law. The intermolecular forces between the molecules of ethanol and water are similar in nature and strength, leading to similar vapor pressures. Therefore, when they are mixed, the vapor pressure of the resulting solution is the sum of the vapor pressures of the individual components, as predicted by Raoult's law. In an ideal solution, the enthalpy of mixing is zero, which means there is no heat absorbed or released during the mixing process.
