Silver bromide growth rates

Bromine and Iodine Compared to chlorine, much less bromine and iodine are produced annually because there are fewer commercial uses for their compounds. Silver bromide and silver iodide are used to coat photographic film. Your body needs iodine to maintain a healthy thyroid gland. This gland produces hormones that control growth and your metabolic rate—the speed at which biochemical reactions occur. Alack of iodine causes the thyroid gland to enlarge, a condition called goiter. Seafood is an excellent source of iodine. So is iodized salt, which contains potassium iodide or sodium iodide in addition to sodium chloride. Because iodine kills bacteria, campers use iodine tablets or crystals to disinfect water.
