Question

Which of the following conditions is true for the formation of solutions?

• A. Same type solute and solvent easily form a solution.
• B. On heating, more solutes are dissolved in a solvent. They easily form solutions.
• C. Small particles dissolve faster in a solvent and easily form solutions
• D. All of the above

Answer 1

The correct option is D All of the above

Same type solute and solvent always form solutions. Example: A polar solute is always soluble in a polar solvent.
Small particles dissolve faster in a solvent and easily form solutions. Example: Salt crystals are easily soluble in water compared to big pieces of salt.
When the solvent is warmed, the tiny particles it is made of move faster. This increases the spaces between them so that there is room for more solute to dissolve. Salt is an example of a solute that changes a little when the temperature of water rises.
