An experiment is conducted to determine how the boiling point of water is altered by adding incremental amounts of sucrose to a volume of water. Students, using a Bunsen burner, first measure the boiling point of 100 mL pure distilled water to use as their control. Then they add sucrose, in 10 gram increments until they reach 100 grams, to 100 mL of water. The solutions are heated and the boiling point at each incremental addition of sucrose is recorded. Which statement is NOT an appropriate hypothesis for this experiment? A) The addition of sucrose to pure water will lower the boiling point. B) The more sucrose added, the greater the concentration of the solution. C) The addition of sucrose will not alter the boiling point of pure distilled water. D) The greater the concentration of sugar in a sugar-water solution, the higher the boiling point.

Respuesta :

Answer:

Explanation:

The addition of a solute to solvent increases the boiling point of the solution . Higher the concentration of the solute , higher will be the boiling point . But if we measure the boiling point of distilled water , since there is no solute in it , there will not be any change in its boiling point .

So following statements are not appropriate  .

A) The addition of sucrose to pure water will lower the boiling point .

Answer:

B the more sucrose added, the greater the concentration o the solution

Explanation: correct
