A city council is debating different alternatives for purifying water from a local reservoir. The

Question

council is considering ion exchange and reverse osmosis. Bacterial contamination of the water
supply is the primary concern, and the council has decided that dealing with this is the main
criteria for their choice. Which decision is the most likely outcome of this debate? (1 point)
They are likely to choose ion exchange because it addresses a wider range of problems,
including bacteria.
They are likely to choose reverse osmosis because it is specifically designed to kill bacteria.
They are likely to choose ion exchange because it is specifically designed to kill bacteria.

Answer 1

The most likely outcome of this debate is: They are likely to choose reverse osmosis because it is specifically designed to kill bacteria.

Reverse osmosis is an effective water purification method that removes a wide range of contaminants, including bacteria, by forcing water through a semipermeable membrane. While ion exchange can address certain contaminants, including some ions and heavy metals, it is not specifically designed to eliminate bacterial contamination as effectively as reverse osmosis.
