JudyYou can drop metals out of water by adding a chemical coagulant such as alum or ferric chloride, which will bind to the metal particles and form larger clumps that settle out of the water. To reach 5ppm of metals in solution, you would need to test the water periodically and continue the treatment process until the desired concentration is achieved.

Which metals does not react with water?
Most metals do not react with water, especially at room temperature. It is easier to state which metals DO react with water. Those would be Li, K, Sr, Ca and Na. Those reacting with hot water (steam) would be Mg, Al, Zn and Cu. Most other metals do NOT react with water.
Example when alkali metals and water go together?
When alkali metals such as sodium or potassium react with water, they form metal hydroxides and release hydrogen gas. This reaction is highly exothermic, often leading to the evolution of heat and formation of a strongly alkaline solution. The reaction between alkali metals and water is generally violent and can even result in the ignition or explosion of the hydrogen gas produced.
What metals are best resistant in salt water?
Metals that corrode in salt water easily include iron and tin.
Are transition metals soluble in water?
Most transition metals are insoluble in water with the exception of some transition metal ions that form soluble complexes, such as copper(II) ions. Transition metals tend to form insoluble hydroxides or oxides when they react with water.
Do metals react in water?
Some metals do react with water. For example, alkali metals like sodium and potassium react vigorously with water to produce hydrogen gas and metal hydroxide. Other metals like iron and aluminum may react slowly with water over time. However, some metals, such as gold and platinum, do not react with water.
