What will dissolve lead?
Lead metal resists sulfuric and phosphoric acid but not hydrochloric or nitric acid; the outcome depends on insolubility and subsequent passivation of the product salt. Organic acids, such as acetic acid, dissolve lead in the presence of oxygen. Concentrated alkalis will dissolve lead and form plumbites.
Will we run out of lead?
Lead is one of the easiest metals to recycle. … Since lead is one of the more common heavy metals we are unlikely to run out even if we develop a thousand new uses for it (there are over 70 million tons of estimated lead reserves in the world today).
Will we ever run out of copper?
Copper and its alloys are totally recyclable. … Whilst we shouldn’t run out, the demand for copper is growing and this may lead to shortages in the future until new deposits can be mined economically.
