A 5.82 g silver coin is dissolved in nitric acid. When sodium chloride is added to the solution, all the silver gets precipitated as AgCl. The percentage of silver in the coin is :

2AgNO_(3)+2NaOH to Ag_(2)O darr+2NaNO_(3)+H_(2)O

What type of reactions are represented by the following equations ? (i) NH_(4)NO_(2) to N_(2) + 2H_(2)O (ii) AgNO_(3) + NaCI to AgCl + NaNO_(3)

A silver coin weighing 11.34 g was dissolved in nitric acid When sodium chloride was added to the solution all the silver (present as AgNO_(3) ) precipitated as silver chloride. The mass of the precipitated silver chloride was 14.35 g. Calculate the percentage of silver in the coin.
