Question

Which of the following will be the result of dissolving a substance?

Answer 1

Answer:

The answer to your question is d.

Explanation:

Chemical changes happen when the substance changes its original properties to form a new one. So option 1 is incorrect.

Dissolving a new substance does not form new substances as I mentioned before. The second option is incorrect.

The third option is also wrong because dissolving a substance does not separate anything.

The fourth option is correct, dissolving a substance allows us to make solutions.

Answer 2

Answer:

The correct options are:

Option C. separating solute particles from the mass of solute

Option D. making a solution

Explanation:

Dissolving of substances is simply a physical change as no new substance is formed and can easily be reversed.

Dissolving of substances does not create new chemicals, it only produces lesser concentration of the substance dissolved

Dissolving of substance results in the separation of the solute Particles as the particles are now free to move about. This is the reason why ionic compounds conduct electricity when in solution or molten state. E.g NaCl dissolves according to the equation

NaCl <==> Na+ + Cl-

So we can see that the particles (Na+ CL-) have separated from the solute itself

Dissolving of substances results in solution. This is true because the solute(substance that is dissolved) dissolve forming a homogeneous mixture call true solution

So, option C and D are correct.

So
