When salt and sugar are added to water ____
|
|
there are no changes in freezing and boiling points
|
|
|
the boiling point stays the same and the freezing point is lower
|
|
|
the boiling point and freezing point are lower
|
|
|
boiling point is higher and freezing point is lower
|
Explanation:
Detailed explanation-1: -The correct answer is c) Boiling point increases and freezing point decreases. Colligative properties of solutions result when a solute is dissolved into a liquid solvent.
Detailed explanation-2: -More heat energy was needed to break the ionic bond in salt solution than the covalent bond in sugar solution so the boiling point of salt solution was higher.
Detailed explanation-3: -Based on the results, when water has salt or sugar added the freezing point will be lower than pure water regardless of whether it was salt or sugar added. The results of this experiment show that the water with salt froze at lower temperatures than the water with sugar.
