Properties and Behavior of NaBr in Water

The video explores whether sodium bromide (NaBr) is an electrolyte or non-electrolyte. It explains that NaBr is an ionic compound, consisting of sodium (a metal) and bromine (a non-metal). When dissolved in water, NaBr dissociates into sodium ions (Na+) and bromide ions (Br-), making it a strong electrolyte. The video concludes that NaBr is highly soluble in water and conducts electricity, confirming its status as a strong electrolyte.
