What is a weak electrolyte?

A chemical compound that does not fully dissociate into ions when dissolved in water, resulting in a weak electrical conductivity.

What makes a salt insoluble?

An insoluble salt is a compound that does not dissolve significantly in water, forming a solid precipitate.

What is a partially soluble compound?

A partially soluble compound dissolves to a limited extent in water, forming a dynamic equilibrium between dissolved ions and solid precipitate.

How do you detect a gas?

Testing for gases involves observing specific reactions and physical changes, such as precipitate formation, color change, or odor. The method used depends on the unique properties of the gas.
