Substance A and substance B are mixed together. To separate the mixture, water is added, and substance A is filtered out. Then, the

Question

remaining liquid is heated to remove the water, leaving substance B. Which statement about substance A and substance B could be
correct?(1 point)
Substance A is rice, and substance B is sugar.
Substance A is salt and substance B is also salt.
Substance A is alcohol, and substance B is salt.
Substance A is sodium and substance B is chloride; they had reacted together as sodium chloride.

Answer 1

The most accurate statement based on the separation method described would be:

Substance A is alcohol, and substance B is salt.

This is because alcohol can be mixed with water, allowing it to be filtered out, while salt dissolves in water. Following filtration, heating the liquid would then remove the water, leaving the salt behind as a solid.

The other options either do not fit the separation method described or are chemically incorrect:

• Substance A is rice, and substance B is sugar. Rice does not dissolve in water and cannot be filtered out in this manner.
• Substance A is salt and substance B is also salt. If both were salt, they wouldn't separate through filtration or heating in the manner described.
• Substance A is sodium and substance B is chloride; they had reacted together as sodium chloride. Sodium and chloride react to form sodium chloride, and they would not separate in the way described.

So the statement about alcohol and salt is the most fitting.
