Question

Do you predict that salt will be able to move across the membrane?

1. Yes, because NaCl is small
2. Yes, because NaCl is ionic
3. No, because NaCl is large
4. No, because NaCl is ionic

Answer 1

Answer: The correct answer is

No, because NaCl is Ionic

Step-by-step explanation:

NaCl can pass through the cell membrane because it is Ionic and separates into Ionic components Na+ Cl+.

Cell membrane are phospholipids bilayers and have hydrophobic tails and face inside of the cells . The fatty acids tails are non polar and only non polar substances can pass through it but salts is a polar molecules because it is an ion and cannot pass.
