Water Conductivity by Julius Breindl https://padlet.com/j_breindl/muib7x16dc9p How salt changes the water en-us 2016-10-05 12:55:29 UTC 2016-10-17 02:25:09 UTC hello@padlet.com Water's properties j_breindl https://padlet.com/j_breindl/muib7x16dc9p/wish/128485992 Water is usually a conductor for electricity in the real world, but distilled water is an insulator, though water that pure does not exist naturally.]]> 2016-10-05 13:58:43 UTC https://padlet.com/j_breindl/muib7x16dc9p/wish/128485992 j_breindl https://padlet.com/j_breindl/muib7x16dc9p/wish/129096810 Water is never an insulator in nature because it is a very good solvent. Water almost always has salt in it, making it an excellent conductor]]> 2016-10-07 12:53:03 UTC https://padlet.com/j_breindl/muib7x16dc9p/wish/129096810 Key Terms j_breindl https://padlet.com/j_breindl/muib7x16dc9p/wish/129097538 Solvent- An element dissolves other substances
Insulator- An element that is poor at conducting electricity
Conductor- An element that conducts electricity well
Salinity- Measure of salts dissolved in the water
Dissolve- To melt or liquefy
Resistivity- The property of resisting (electrical flow)
Conductivity-The power of conducting electricity
Ions- An electrically charged atom formed by the loss or gain of a valence electron, gives a positive or negative charge.
Valence Electron- An electron in the outermost shell of an atom.
Distilled Water-  Water that is free from impurities.

Agricultural output of highly saline water is also adversely effected.]]> 2016-10-07 23:41:18 UTC https://padlet.com/j_breindl/muib7x16dc9p/wish/129257604 Limits on water Salinity j_breindl https://padlet.com/j_breindl/muib7x16dc9p/wish/129814143 The EPA has no official limits on Saline water,  the definitions are as follows
Fresh Water- less than 1,000 ppm
Slightly Saline Water- 1,000 ppm-3,000 ppm
Moderately Saline Water- 3,000 ppm- 10,000 ppm
Highly Saline Water- 10,000 ppm- 35,000 ppm]]> 2016-10-11 14:12:41 UTC https://padlet.com/j_breindl/muib7x16dc9p/wish/129814143 Works Cited j_breindl https://padlet.com/j_breindl/muib7x16dc9p/wish/131022456 Human Activities.

Certain irrigation patterns also cause increased salinity.]]> 2016-10-17 02:20:12 UTC https://padlet.com/j_breindl/muib7x16dc9p/wish/131023356
