What type of support is needed for the cellulose acetate membrane in reverse osmosis?

Options

  1. AA support that is impermeable to water
  2. BA support that is permeable to water
  3. CA support that is permeable to impurities
  4. DA support that is permeable to ions

Correct answer

B. A support that is permeable to water

Step-by-step solution

The paragraph doesn't specify the exact nature of the support, but it suggests that the support is suitable for the cellulose acetate membrane used in reverse osmosis.
