Question

Which methods could be used to dilute a solution of sodium chloride (NaCl)? Select all that apply.

Add more NaCl to the solution.

Add more water to the solution.

Remove a small amount of the solution and mix it with water.

Heat the solution to evaporate some of the water.
Label A-F based on the table using C for concentrated and D for dilute.

A 3-column table with 3 rows. Column 1 is labeled Acid slash base with entries upper H c l, Upper N a upper O upper H, Upper H subscript 2 upper S upper O subscript 4. Column 2 is labeled Molarity with entries 12 M and 0.5 M, 0.01 M and 6.0 M, 0.05 M and 10 M. Column 3 is labeled concentrated slash dilute with entries A and B, C and D, E and F.

Answer 1

Methods that dilute a NaCl solution (select all that apply)
- Add more water to the solution. (Yes)
- Remove a small amount of the solution and mix that removed portion with water. (Yes — that produces a more dilute solution of the sample.)
- Add more NaCl to the solution. (No — this increases concentration.)
- Heat the solution to evaporate some water. (No — this removes solvent and makes it more concentrated.)

Labels A–F (C = concentrated, D = dilute)
- A = C
- B = D
- C = D
- D = C
- E = D
- F = C
