Can you help me with the following chemistry questions?

Question

1. why does dipping meat in salt preserve it?
2. why can't we save water by using seawater to irrigate our crops?
3. what happens when a thirsty person drinks salt water to try and quench their thirst?

Answer 1

i will not answer it exactly but i will give you a hint. the process you need to look up is osmosis. cell density and the density of salt vs fresh water. Salt is not toxic to bacteria. That is not the right answer for number 1.

Answer 2

HEY! If your thirsty and you try to drink salty sea water your only causing even more thirst. You see, too much salt has the power to dehydrate your body. So if your stranded in the ocean, never drink the water or you'll die quicker. As for using salt water on crops, i just know that it kills plants. Also the salt gets into ground water which most people use to drink. Not sure why it preserves meat. Though it does keep snails off your hamburger.lol, hope I helped!

Answer 3

1) Salt is toxic. Appled to meat, kills the bacteria.

2) Salt is toxic. It kills nearly all land plants, there are a few grasses and such that can tolerate some salt.

3) The body will become dehydrated as it pulls more and more water out of tissues trying to get rid of the salt.

People need salt, but not all that much.

Answer 4

The salt in all three questions draws out moisture so that is why the meat is preserved. You would have the driest dirt around so you couldn't use it in a crop and drinking it would dry out your mouth defeating the purpose of drinking something.
