2500 PPM

What does it mean by "in Colorado, water having up to 2,500 ppm of salt is used for irrigating crops." Is that a requirement from somewhere? Or is that just what's available?

Answer

Well, it would be sort of obvious to me that water up to 2,500 ppm of salt is usable because anything higher would make the plants die Gradster1 21:48, 6 January 2007 (UTC)[reply]

...this is true but as you wouldnt think it will enrich a type of soil called bed rock soil —Preceding unsigned comment added by 75.63.144.121 (talkcontribs)

Where is it located?

Is this sea water? Is it our common Ocean? —Preceding unsigned comment added by 69.15.80.210 (talk) 15:44, 9 October 2007 (UTC)[reply]

To be added?

Why

Normally, moderately or highly salinated water is of little use to humans. Humans cannot drink salinated water directly, nor is it suitable for irrigating crops.

Why can't humans drink salty water? We eat salty foods all the time. 207.179.157.81 (talk) 23:28, 23 June 2008 (UTC)[reply]

This may be weird but, I tried drinking salty water and nothing bad happened to me. 207.179.153.65 (talk) 19:37, 19 December 2008 (UTC)[reply]
I'm gonna remove that line. It's pretty non-factual.--SlimNm (talk) 18:40, 24 December 2010 (UTC)[reply]

Solubility

I was hoping to find an article on the solubility of salt in water, but don't know where to find it. Does H20 become more soluble at higher pressures (like in science fiction literature) or does it become less soluble? That is, if we increase the pressure but keep the temperature the same, can you mix in more salt, or is there a point where it precipitates or suddenly separates and comes out of solution? If anybody knows the answer, please post it here, or post a link where I can go to find out. There's bound to be a lot of studies on this.

Also, I wanted to read up on the electrical conductivity of salt mixed into water. If there is more salt, does it increase its electrical conductivity, or is there a point where electricity doesn't pass through? All of this may be obvious to you, but I went here to find out the answer, and couldn't get any farther. Dexter Nextnumber (talk) 08:03, 10 January 2013 (UTC)[reply]
