Saline solution is used to keep contact lens sterile. Salt is also used to preserve meat from bacteria. If it's anti bacterial, wouldn't it be beneficial to put in an open wound? After all alcohol on a wound is painful, but people apply alcohol to a wound?
What is it about salt that makes it anti bacterial? Does it change ph? I've also heard sugar is anti bacterial, that's why hard candy will not spoil. How about packing sugar on a wound to kill bacteria?
Why does concentrated sugar avoids spoilage. Again, is it ph?, or something else?
