The organic nitrates, including nitroglycerin, isosorbide dinitrate and isosorbide mononitrate, act as prodrugs for nitric oxide (NO) which is a potent vasodilator gas. Nitric oxide activates guanylyl-cyclase in vascular endothelial cells, which increases intracellular cyclic GMP and thereby reduces intracellular calcium concentrates and dephosphorylates myosin light chains causing relaxation of smooth muscle cells.
Silver nitrate is used as an indicator-when dissolved the ionic bond holding the Silver atom to the rest of the molecule is broken letting loose positive silver ions into the solution. These react with the lone negative halogen ions which are formed by the hydrolysis of haloalkanes, to form a visible precipitate.This indicates that hydrolysis has occurred and the colour can show the which haloalkane was hydrolysed.Yellow-Iodoalkane Cream-Bromoalkane White-Chloroalkane.ilver nitrate is used as an indicator-when dissolved the ionic bond holding the Silver atom to the rest of the molecule is broken letting loose positive silver ions into the solution.
