1 Answer Sorted by: 1 If you want 10 ppm copper in 2 liters of water, the best way to make it would be to start with some soluble copper salt, like CuSOX4⋅5HX2O C u S O X 4 ⋅ 5 H X 2 O, make up a convenient concentration (like 1%), then dilute it to 10 ppm. As was mentioned in the comments, copper metal is not noticeably soluble in water.

1. Introduction During industrial production, oils such as lubricating oil and engine oil tend to age and deteriorate due to longterm contact with additives, metal powder, oil chips, and other impurities [1]. Eventually, these oils need to be replaced to avoid damage to equipment and losses in efficiency [2].

According to Henry's law, for an ideal solution the solubility, Cg, of a gas ( × 10 −3 mol L −1, in this case) is directly proportional to the pressure, Pg, of the undissolved gas above the solution ( kPa in this case). Because both Cg and Pg are known, this relation can be rearranged and used to solve for k .
