A thistle funnel is commonly used in the process of osmosis to create a barrier between the two solutions, allowing only water to pass through via osmosis while preventing the solutes from mixing. This setup helps to observe the movement of water molecules across a selectively permeable membrane and measure the rate of osmosis under controlled conditions.
The most usual use for a thistle funnel is to add liquid during gas preparations, for which use it is usually inserted into one hole of a two hole stopper. (The other hole contains the delivery tube.) If gas is to be delivered to the collecting vessel, you should ensure the base of the funnel tube is covered by the liquid in the flask. Inserting the thistle funnel through the stopper must be done extremely carefully, using a hollow cork borer, as the glass stem is extremely easy to snap. I would advise that this fitting is not attempted without someone to show you the correct procedure.
A filter paper is typically held in a funnel during filtration. The funnel is often placed in a ring stand or held by a clamp to support it during the filtration process.
Salt is used in osmosis to create a concentration gradient that drives the movement of water molecules across a semi-permeable membrane. This helps regulate the flow of water in a biological system or can be used to separate substances through the process of reverse osmosis.
No, parchment paper is not typically used in osmosis experiments as it is not a semipermeable membrane required for the process. Osmosis usually involves a selectively permeable membrane that allows solvent molecules to pass through while restricting the passage of solute molecules.
A thistle tube is a piece of laboratory glassware consisting of a shaft of tube, with a reservoir and funnel-like section at the top. Thistle tubes are typically used by chemists to add liquid to an existing system or apparatus.The thistle tube shaft is designed to allow insertion through a small hole present in some stoppers, permitting the tube to be inserted into a container such as an Erlenmeyer flask.

Thistle tubes are usually used in experiments involving semi-permeable membranes. Osmosis and diffusion can be illustrated well. Thistle tubes are also used in separation experiments as well as other chemical applications.
A filter funnel is a laboratory funnel used for separating solids from liquids via the laboratory process of filtering.

A filter funnel is used to separate liquids and solids in a laboratory. It is used in the filtering process by folding a disk shaped filter paper into a cone an putting it in the funnel. Liquid will pass through but solids will not.
osmosis is the process of water moving from high concentration to low concentration through semi-permeable membranes. it is used to get water to the plant for photosyntesis
