Do Metals Dissolve In Water?

It depends what the metal is- or what's in the water.

Lithium and sodium, both alkali metals, react readily in water as they can easily oxidize (give away an electron) in the presence of hydroxide (H+) and hydronium (OH-) ions naturally present in regular water.  Reactivity increases going down the group, so rubidium and cesium are so reactive in water that it causes an explosion (youtube it).

Most metals need do be dissolved in acidic water solutions- the ability for this to occur depends on the electronic configuration of the metal and the acidity (amount of hydroxide) of the solution it's in.

Decidedly metals do not dissolve in H₂O. Corrosion is not an indication of a solute - solvent system but an acid or base reaction. If septic insists H₂O does dissolve metals, then I would have to ask septic why gold coins at the bottom of the ocean do not dissolve but are nearly in original condition?

Some metal do not dissolve in water.Iron oxide is insoluble .Insoluble metals are called bases.
  The solubilty rules says:all soduim,potassium,ammonium and nitrate are soluble.
All chloride,bromide, and iodide are soluble expect for SILVER CHLORIDE,SILVERBROMIDE AND SILVERIODIDE.
Sulphate are soluble EXPECT BARIUM SULPHATE AND CALCIUM SULPHATE.
HYDROXIDE AND CARBONATE ARE INSOLUBLE EXPECT FOR SODIUM,POTASSIUM AND AMMONIUM.

Are you guys morons?  Have you any idea what a solution, and hence dissolving, are?

Metals do not dissolve in water. They can react with water and corrode but they do not dissolve.

Metals DO dissolve in water. Oxygen in the water cause corrosion. That why in big boilers, you need to add chemicals to deter the corrosion. It may take more than your lifetime if you just submerged a piece of metal in water but when you add heat, it can destroy a new boiler in less than two years.

I don't think so.. There are so many ships or many metal things you can find deep in a sea buried or drowned decades ago =(

No they do not metal is not like salt or sugar, and it is not a base.

Yes they do. The collides with the metal little by little then like the titanic it becomes dust
