NaClO solutions, the following species are thought to be present when the system is in equilibrium.[30] [snip] The free chlorine is thought to be modulated by pH and NaCl as indicated by mercury-chlorine byproducts.<\/p>\n HOCl \u2194 H+ + OCl\u2212 The last sentence is critical.<\/p>\n Cl\u2212 ions (from the NaCl) play a rarely mentioned role<\/p><\/blockquote>\n The salt in the pool contributes to the generation of chlorine gas from hypochlorite. <\/p>\n Yikes!!!! This would explain the fact that galvanized pool fittings corrode badly in a salt pool. A lot of pool companies websites say that there is not enough salt to affect metal. But turn around and admit that corrosion of metal fittings around the pool is a common problem with a salt pool.<\/p>\n I would bet that it’s not the salt concentration it’s the chlorine gas being generated. Chlorine gas is incredibly corrosive. And if your metal components are corroding, so are you. And what is it doing to the plants surrounding your pool? Or the paint on your house? Or your dog? Cat? Kids?<\/p>\n So back to my original question: how much salt is in a salt pool? <\/p>\n Well it’s about 60 millimolar. And I finally found a graph showing the effect of increasing salt concentration on plants. They did a pretty good job with trying to take into account the chloride and sodium contributions of the various media components so I think this is a pretty good study. \nThe point is that for the crop plants tested, it is safe to use 60mM salt (your salt pool water) for irrigation (of course only once the chlorine generator and the chlorine gas has been removed :-) ). And, especially if you are irrigating using rainwater in addition to the water from your salt pool. Or, better yet, also using your pool to collect rainwater.<\/p>\n Bob<\/p>\n","protected":false},"excerpt":{"rendered":" I have been searching online trying to get a feel for how much salt is in a salt pool.

\n“hypochlorous acid (chlorine) is converted back to salt”
\nFirst of all: hypochlorous acid is not chlorine in either chemistry or name. Secondly: if hypochlorous acid was just converted back to table salt it really wouldn’t poison everything in your pool. Thirdly: chlorine would gas off into the atmosphere.

\nHOCl + Cl\u2212 + H+ \u2194 Cl2 + H2O
\nThe ratio of Cl2 : HOCl : OCl\u2212 is pH dependent.[31] The above equations show that the “byproduct” Cl\u2212 ions (from the NaCl) play a rarely mentioned role, without them there would be no available chlorine in the solution.<\/p><\/blockquote>\n<\/a><\/p>\n
