How much salt is needed to kill bacteria?

It depends on the bacterium. Actually there are halophiles which like very high salt concentrations.\nIt also depends on the strain. So there are strains of E.coli which stop growing at around 0.6 M NaCl and others at 1.2 M, though it also depends on the contribution of the rest of the solutes to the osmolality of the medium.

1 gram of salt to 9 mL of water if i'm not mistaken. i forget if 1 gram solid salt is equal to 1 mL of water, but basically, to get normal saline, you have to mix 1 part salt to 9 parts water.

I would say an isotonic solution of salt (0,9%) is good enough and no sodium bicarbonate is needed.

The Dead Sea waters contain salts of magnesium chloride (53%), potassium chloride (37%) and only 8% sodium chloride, which is normal table salt. Magnesium chloride and pottasium chloride give the Dead Sea salt a bitter taste that makes it undesirable to consume, but not poisonous. \n\nHowever, since raw sewage runs into the Dead Sea it probably is unsafe to drink. The salinity may kill most of the bacteria, but there are trace metals that are hazardous that are found in these waste waters. Agricultural chemicals are another problem. \n\nSome Dead Sea salts are mined for 'therapeutic" uses, likely becuase some of the minerals in the salts are thought to be good for the skin. \nhttp://www.nextag.com/bulk-sea-salt/search-html

the bacteria's cell membrane is semi permeable to certain molecules.  bacteriacides probably have some form of "nutrient" in them to confuse the bacteria into taking it in.  It is sort of like rat poison.

Salt only helps the boiling point rise a little. It will boil more rapidly. It will not decrease time it takes to reach boiling point.

Not much, actually-You dont want something that kills the bacteria in the mouth, because they are the primary protection against even worse things.  People who have to take very high doses of antibiotics often loss the bacteria in the mouth, and then have things like thrush, yeast, even massive fungal infections-and these are extremely hard to treat.  Toothpaste just scrapes the bacteria off the tooth, so the acidic waste products of the bacteria dont eat away the enamel.

Salt - sodium chloride.\n\nIf you need something a bit more unusual, I believe there is imitation salt which is potassium chloride.

The amount of salt that we eat has a direct effect on our blood pressure. The more salt we eat, the higher our blood pressure. This is true, not only in people with high blood pressure, but also in people with normal blood pressure. A high salt intake also causes other health damage such as greater retention of water in your body, which leads to swelling of the ankles. Too much salt also worsens thinning of the bones (osteoporosis), asthma and kidney disease and is closely related to cancer of the stomach. Therefore, everyone should cut the amount of salt they eat.\n\nThe Department of Health and Food Standards Agency recommend that everyone should cut their salt intake from the current amount of 10 to 12 grams of salt a day to 5 to 6 grams a day, or less. If you can reduce salt intake more, this will lower your blood pressure further

Na2SO4 + H2O\n\nYou always get a type of salt plus water in acid-base neutralization.

i am not sure but every pools i've visited use chlorine and people say it kills bacteria

Regular salt will be just fine my friend.\nGood Q\nGood luck

salt aggravates rheumatic pain so if u can survive w/o salt then do it.. otherwise, u'll suffer more & more pain..

pasteurisation does not attempt to kill all microorganisms. it is a process strictly for food products, where these products are heated above 70 celcius for an extended period to kill MOST common bacteria.\n\nsterilisation can include heating, chemical doping, or radiation, all of which are meant to completely eliminate living things on the object to be sterilised. purposes include surgery, or electronic manufacture.

Dependent upon the wound, it's either sterilized water/saline mix or Bettadine.\n\nSoap doesn't usually kill germs but it helps slough them off along with dead skin cells.

NaCl needs to be at the correct concentration, as it is needed to ensure that enzymes etc. work correctly.  It allows the cells to have the correct concentrations of sugars etc by influencing water entry by osmosis.\n\nA cell can take up a linear plasmid, but probably won't be able to propagate more copies if is isn't annealed, unless the correct DNA Ligase enzymes happen to be available in the cell.
