The difference between a conical flask and an iodine flask (determined iodine triangular beaker)

1. Different uses
The purpose of the iodine flask: it is generally a conical flask dedicated to the determination of iodine. It can also be used as a reaction vessel for other volatile substances.
Erlenmeyer flasks are generally used in titration experiments. In order to prevent the titrant from splashing out of the bottle when it drops, causing experimental errors, the bottle was stirred on a magnetic stirrer. Erlenmeyer flasks can also be used in ordinary experiments to prepare gases or as reaction vessels. Its conical structure is relatively stable and will not tip over.
2. The affiliation is different
The iodine volumetric flask belongs to the conical flask, which is a kind of conical flask. Use a ground stopper on the mouth of the conical flask, and add a water seal groove to become an iodine volumetric flask.
3. Different usage
Iodine volumetric flask: After adding the reactants, close the stopper tightly, and add an appropriate amount of water to seal the stopper to prevent iodine volatilization. After standing for a certain period of time, slowly open the stopper, and let the sealing water flow into the conical flask along the stopper, and then use water Wash the iodine solution on the bottle mouth and stopper into the bottle.
Erlenmeyer flask: In order to prevent the titrant from splashing out of the bottle when it drops, causing experimental errors, put the bottle on a magnetic stirrer to stir. You can also hold the neck of the bottle with your hand and shake it with your wrist to stir evenly.
In addition to being convenient to add a stopper, its long neck can also slow down the loss during heating and avoid chemical spills; as for its flat and wide bottom, it allows the conical flask to hold more solution and facilitates stirring with a glass rod. And allow the Erlenmeyer flask to lay flat on the table.
