Silver ions can be found in some of the city water piped into homes. The average concentration of silver ions in city water is 0.028 ppm. (a) How many milligrams of silver ions would you ingest daily if you drank eight glasses (eight oz/glass) of city water daily? (b) How many liters of city water are required to recover 1.00 g of silver chemically?
It is sometimes asserted that carbonates are soluble instrong acids because a gas is formed that escapes (CO2).Suppose that CO2 were extremely soluble in water (as, forexample, ammonia is) and therefore it did not leave thesite of the reaction, but that otherwise, its chemistry wasunchanged. Would calcium carbonate be soluble in strongacids? Explain.
