Which statement best describes the conductivity of weak electrolytes, such as weak acids and bases?
a) weak electrolytes do not dissolve in water and can not conduct electricity.
b) weak electrolytes dissolve and partially dissociate in water providing charged ions to conduct electricity.
c) weak electrolytes dissolve and completely dissociate in water providing charged ions to conduct electricity.
d) weak electrolytes dissolve and does not dissociate in water providing no charged ions to conduct electricity.

B) Weak electrolytes dissolve and partially dissociate in water providing charged ions to conduct electricity.

Explanation: Weak electrolytes are those substances which do not dissociate completely when dissolved in water. They dissociate but then associate back and thus their dissociation is shown by an equilibrium sign. Example:

The charged species formed helps in the conduction of electricity.

Strong electrolytes are those substances which dissociate completely when dissolved in water. Their dissociation is shown by a forward arrow. Example:

The charged species formed helps in the conduction of electricity.

the major pests we deal with are insects, weeds and fungal diseases. a pesticide is a product, whether organic or chemical, used to kill the target pest. there are other techniques gardeners should use that can prevent the severe infestations that make the use of pesticides necessary
