The addition of ethanol, which is fully miscible in water yet, less polar than Water reduces its solubility. This reduction of solubility results in precipitation of least soluble salts first or the salt which is not soluble in solvents less polar than water.
Pole pockets on banners are something that can cause a bit of confusion. This is compounded by the fact that some companies do things differently when producing banners with pole pockets.
A pole can be inserted into the pole hem to keep the flag attached. The pole hem can be either on the top of the flag so it can be hung on a horizontal pole like a banner or the pole hem can be created along a side of the flag so it can be hung on a vertical pole.ylon, cotton, satin, and polyester are among the materials available. Indoor construction can include additional features such as fringe and gold tassels. Depending on the how the flag is to be displayed grommets or a pole hem may work best.
