Which of the following is a consequence of dissolving a solid in a liquid?
A
The liquid evaporates completely, leaving only the solid behind.
B
The solid's particles disperse uniformly throughout the liquid, forming a solution.
C
The solid remains unchanged and settles at the bottom of the container.
D
The solid reacts with the liquid to produce a gas.
Verified step by step guidance1
Understand the process of dissolving: When a solid dissolves in a liquid, the solid's particles separate and spread out evenly throughout the liquid.
Recognize that dissolving results in a homogeneous mixture called a solution, where the solid is called the solute and the liquid is the solvent.
Eliminate options that do not describe dissolving: evaporation of the liquid leaving solid behind is a physical change but not dissolving; solid settling means no dissolution; reaction producing gas is a chemical change, not simple dissolving.
Identify that the correct consequence of dissolving is the dispersion of solid particles uniformly throughout the liquid, forming a solution.
Conclude that dissolving involves the interaction between solute and solvent particles leading to a uniform mixture, which matches the correct answer.
