Upon reaction with excess sulfamic acid, HSO3NH2, a 0.121g sample of a mixture of sodium nitrite, NaNO2, and sodium chloride, NaCl, produced 28.3 mL of nitrogen gas collected over water at 25.3 degrees Celsius and at a barometric pressure of 738 m
Why is it more difficult to precipitate cupric acetate (verdigris) than cupric carbonate hydroxide (malachite)
Suppose we have a solution of lead nitrate, Pb(NO3)2(aq). A solution of NaCl(aq) is added slowly until no further precipitation occurs. The precipitate is collected by filtration, dried, and weighed. A total of 16.54 g of PbCl2(s) is obtained from
