Which is correct poinsettia or poinsettia? When solutions of silver nitrate and potassium bromide are mixed, a pale yellow precipitate is formed. That means that there will be more attraction between a lone pair on the water and a carbon atom attached to a chlorine atom than if it was attached to an iodine atom. The light sensitive silver halides, silver chloride, silver bromide and silver iodide, are used to make photographic film and photographic paper.
