Final answer:
LiCl (lithium chloride) can most likely be used to treat canine epilepsy akin to KBr (potassium bromide) due to their similar properties as compounds of alkali metals paired with halogens, and lithium's established use in medical treatments.
Step-by-step explanation:
On the basis of periodic properties, lithium chloride (LiCl) is a compound that can most likely also be used to treat canine epilepsy. Considering KBr, or potassium bromide, is used for this purpose and it's an ionic compound consisting of an alkali metal (potassium) and a halogen (bromide), we can draw parallels to lithium chloride, which is made up of another alkali metal (lithium) and a halogen (chloride).
Lithium, like potassium, has a history of use in medical treatments for conditions such as manic-depressive, or bipolar, behavior. Just as KBr functions in the medical treatment for epilepsy in dogs, compounds from the same alkali metal group, such as LiCl, may exhibit similar therapeutic properties due to their comparable chemical characteristics. It should be noted, however, that any changes in medication should be prescribed and supervised by a qualified veterinarian.
