Multiple Choice
Which statement best describes the relationship between conductivity and the ease with which a salt dissolves in water?
A
Salts that do not dissolve easily in water produce solutions with higher conductivity.
B
Salts that dissolve easily in water generally produce solutions with lower conductivity.
C
There is no relationship between how easily a salt dissolves and the conductivity of its solution.
D
Salts that dissolve easily in water generally produce solutions with higher conductivity.
검증된 단계별 안내1
Understand that conductivity in aqueous solutions depends on the presence of free ions that can move and carry electric charge.
Recognize that when a salt dissolves in water, it dissociates into its constituent ions, increasing the number of charge carriers in the solution.
Realize that salts that dissolve easily produce more ions in solution, which generally leads to higher conductivity.
Note that salts that do not dissolve well produce fewer ions in solution, resulting in lower conductivity.
Conclude that there is a direct relationship: the easier a salt dissolves (more ions in solution), the higher the conductivity of the solution.
