Determine the mass percentage of chloride ion in the seawater if its density is 1.025 g/ml?
The mass percentage of chloride ion in a 25.00 mL sample of seawater was measured by titrating the sample with silver nitrate precipitating the silver chloride. It took 42.58 mL of 0.2997 M silver nitrate solution to reach the equivalence point in the titration.
AgNO3 (aq) + NaCl (aq) ==> AgCl (s) +NaNO3(aq)
