Verified step by step guidance1
Understand what halide ions are: halide ions are negatively charged ions of halogen elements, such as chloride (Cl\^-), bromide (Br\^-), and iodide (I\^-). These ions commonly dissolve in water, especially in environments influenced by saltwater.
Consider the sources of halide ions: halide ions are abundant in seawater because of the high concentration of salts like sodium chloride (NaCl). Therefore, water samples near saltwater bodies are more likely to contain dissolved halide ions.
Analyze each water sample option: freshwater mountain springs typically have low concentrations of dissolved salts, distilled water is purified and free of ions, and rainwater in rural areas is generally low in dissolved ions unless contaminated.
Recognize that water collected near a saltwater ocean is exposed to sea spray and salt dissolution, which increases the likelihood of halide ions being present in the water sample.
Conclude that the sample collected near a saltwater ocean is most likely to contain dissolved halide ions due to the proximity to a natural source rich in halide salts.
