Because of the electro negativity
Yes, if a suspension is filtered, particulate matter will be filtered out. This does not happen to a solution.
seawater solution or suspension
A solution is a homogeneous liquid, a suspension is not homogeneous. A suspension is not a true solution.
Orange juice from concentrate would be a solution, although real orange juice is neither a solution or a suspension. The major difference between solution and suspension is that a solution is a homogeneous mixture, and a suspension is heterogeneous.
seawater solution or suspension
A mixture may be a solution, a suspension, etc.
Biscuit is a solid, not a solution or suspension.
suspension
Suspension will have residue after filtration, but solution will not.
solution
A solution is a homogeneous liquid, a suspension is not homogeneous.
It is a solution.
