Explain why a negatively charged chloride ion has trouble penetrating a cell membrane?

it would really help if someone explained to me why it has trouble getting through!?

well, I guess, it's YOUR search ;)

think about the properties of the membrane? Why do we have it? Why is it usefull?

Cis or trans? That's what matters.

Think also about the chemistry of that ion in water. What interactions are going on and how do they stabilize the ion-water interaction? What happens to those interactions when the ion enters a membrane?
