Want this question answered?
The concentration is very variable; as an indication 1 g/L.
The mean concentration of iodine in sea water is 0,064 ppm.
4ml/1000 = approx 4000 ppm, depending on the final volume after adding 4ml to 1000 ml water
Assuming you mean a concentration of 0.023 as a mole fraction... 0.023 is equivalent to 23000 ppm
Concentration of ozone is about 380 ppm. This is the natural range of ozone.
You prepare a primary solution then dilute portion of your solution down to the required concentration. For example, you want a 10 ppm salt solution (10 mg/L), you dilute 1 g of salt in 1 L of water you get 1000 ppm salt solution. You take 10 ml of your salt solution (0.01 g salt in 10 g) and add in additional 980 ml of water then you get a 10 ppm weight solution.
The concentration is very variable; as an indication 1 g/L.
Mango trees shouldnot be watered with water from wells containing 2,300 ppm ormore of salt.
the amount of salt required depends on how much water is in the pool You will need enough salt to reach a concentration of 4000 ppm (parts per million) to start. Have the water tested for salt content at your pool shop (usualy free), then add then add enough to reach 4000 ppm.
The best way would be to put a shovel full of dirt in a bucket of clean water ant have the water tested for salt content, However the concentration of salt in a salt water pool is very low and would be unlikely to cause any problems to the surounding soil .Most chlorine generators require a salt content of between 2,500 to 6,000 parts permilion of salt to water. human tears contain about 9000 ppm. once you have more then 1000 ppm of dissolved salts in water it is saline; ocean water contains about 35,000 ppm of salt.
Make sure your water is balanced and add salt (sodium chloride). You need to purchase a saltwater chlorine generator and you'll need to calculate the amount of salt you need. You would need to bring your pool salt content up to 3,000 ppm. Concentration is the amount (by weight) of salt in water and can be expressed in parts per million (ppm). Here are the classes of water: * Fresh water - less than 1,000 ppm * Slightly saline water - From 1,000 ppm to 3,000 ppm * Moderately saline water - From 3,000 ppm to 10,000 ppm * Highly saline water - From 10,000 ppm to 35,000 ppm Ocean water has a salinity that is approximately 35,000 ppm. http://www.windows.ucar.edu/tour/link=/earth/Water/dissolved_salts.html&edu=high There is now a system with a healthier salt available Magnesium and Potassium Chloride. it is more expensive but in my opinion it is also much better and halthier than Sodium chloride.

>30ppm in 100g =? mcg in 1g
The safe limit for salt in drinking water is somewhat debatable. In the United States, 1000 ppm is the limit for humans while 2000 ppm is the limit for livestock or watering of crops.
The concentration of oxygen in water is 88,88 %.
True salt water pools have the same parts per million (ppm) as sea water which is roughly 35,000 ppm. We have a salt taste threshold of around 3,500 ppm and our eyes have about 7,000ppm. Most chlorine generators require a salt content of 3,000-5,000 ppm in the pool. You will feel the salt in a true salt water pool, most people don't notice the salt in a pool with a chlorine generator.
Do you mean to say that you have a fresh water pool with a Chlorine Generator which uses salt? Or do you in fact have a salt water pool? bob...
The mean concentration of iodine in sea water is 0,064 ppm.
