Glycerol boils at a higher temperature than water. What does this indicate about the attractive forces of glycerol?
2 answers:
Answer: Glycerol has more attractive forces as compared to water.
Explanation:
Boiling point is the temperature at which vapor pressure of the liquid becomes equal to atmospheric pressure.
Boiling point depends on the strength of inter molecular forces.
The molecules of glycerol are more strongly bonded through hydrogen bonds as there are three OH groups.
But in water , only on e OH group is present and thus extent of hydrogen bonding is less.
Thus we can conclude that glycerol has more attractive forces as compared to water.

Answer:
The true statements are:
The solution is acidic
The pH of the solution is 14.00 - 10.53.
Explanation:
The pH of the solution is defined as negative logarithm of hydrogen ion concentration present in the solution .
- The pH value more 7 means that hydrogen ion concentration is less ,alkaline will be the solution.
- The pH value less 7 means that hydrogen ion concentration is more ,acidic will be the solution.
- The pH value equal to 7 indicates that the solution is neutral.
The pOH of the solution is defined as negative logarithm of hydroxide ion concentration present in the solution .
The pOH of the solution = 10.53
The pH of the solution = ?
Here, the pH of the solution is less than 7 which means that solution acidic.
