I have been reading through the Adaptive Payment API documentation from PayPal's developer page here, but I have not seen any indication of when the receiver would receive their funds.
Salt is, of course, the most common substance found in sea water, but it is far from being the only one. In fact, sea water is actually quite rich in mineral solids. The solids dissolved in sea water vary from about 1 per cent where rivers enter the sea to about 4 per cent where the circulation of water is partly restricted, but they average about 3.5 per cent (one hundred pounds of sea water, if boiled away, will leave behind close to 3.5 pounds of solids). Most of this is ordinary salt -- sodium choloride.
Seawater, or salt water, is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5% This means that every kilogram of seawater has approximately 35 grams of dissolved salts. Average density at the surface is 1.025 kg/L. Seawater is denser than both fresh water and pure water because the dissolved salts increase the mass by a larger proportion than the volume. The freezing point of seawater decreases as salt concentration increases. At typical salinity,
