Answer: The correct answer is
No, because NaCl is Ionic
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.
