Entropy change for dissolving salt in water?
This question isn't very complete, but if you meant what is the solute or solvent, the water would be the solvent because there is more water than salt. In this case, the salt is the solute. If there...
What type of solution has the highest concentration of water molecules?
That is what is known as an aqueous solution.
Is entropy of water is higher than entropy of ice?
Yes, the entropy of water is higher than the entropy of ice because water is in a more disordered state compared to ice, which has a more ordered and structured arrangement of molecules. Entropy is a measure of disorder in a system, so the more disordered the state, the higher the entropy.
Which aqueous solution has the highest boiling point?
The aqueous solution with the highest boiling point is the one with the highest concentration of solute particles, such as salt or sugar, dissolved in water.
How does the entropy of a system change for condensation of water?
The entropy of a system typically decreases during the condensation of water. This is because the molecules of water vapor become more ordered as they transition into the liquid state, reducing the overall disorder (entropy) in the system.
Which form of water has the highest entropy?
Water vapor has the highest entropy compared to liquid water and ice because gas molecules have more freedom of movement and therefore more possible microstates, resulting in higher entropy.

Why NaCl is very soluble but not CaO is only slightly soluble in water?
Its all to do with enthlapy and entropy. Anything which is soluble usually has a negative standard enthlapy of solution - the energy involved when 1 mole of solute dissolves in a solvent to give an infinately dilute solution. However, NaCl has a slightly positive enthalpy of solution, yet it dissolves. The reason for this is entropy - the change in the amount of disorder. When NaCl dissolves in solution, there is more chaos, more molecules within the solution. Any process that has a large positive entropy change will be favourable - spontaneous and can occur (reaction will 'go'). However, with CaO, the Ca2+ formed in solution has a high affinity (attraction to) for water molecules, hence a lot of water molecules are arranged orderly - less chaos and hence a negative entropy. This should in effect make the compound insoluble, however, the slight solubility is due to it still having a negative enthalpy change of solution - hence despite entropy it is still slightly soluble. (You may be asking how is dissolving CaO possible if entropy is negative? The entropy of the system maybe negative, but the entropy of the surroundings is positive (dissolving gives out heat - exothermic), hence the overall entropy (sum of both entropies) is positive and the reaction will 'go'.

Why does an NaCl solution freeze at lower temperature than water but boils at higher temperature than water?
NaCl solution freezes at lower temp. than water but boils at higher temp.than water
How does the entropy of the system change when equal volumes of ethanol and water are mixed to form a solution?
The mixing of ethanol and water leads to an increase in entropy because the two liquids become more randomly dispersed at the molecular level compared to when they were separate. The increase in disorder allows for more ways to arrange the molecules, resulting in higher entropy of the system.
Which has maximum entropy of vaporization?
The compound with the highest entropy of vaporization is likely water (H2O), as it has a relatively high boiling point and strong hydrogen bonding interactions that need to be overcome to transition from liquid to vapor phase. This results in a high enthalpy change and thus a high entropy of vaporization.
How does the concentration of water differ in the solution?
The concentration of water in a solution is highest in a dilute solution and lowest in a concentrated solution. This concentration is affected by the amount of solute present, with a higher solute concentration leading to less water present in the solution.
What describes the phases of water Water expands as it changes from a solid to a liquid?
the entropy of water is higher than the entropy of ice.
How does the entropy of a system change for condensation of water?
The entropy of a system typically decreases during the condensation of water. This is because the molecules of water vapor become more ordered as they transition into the liquid state, reducing the overall disorder (entropy) in the system.
