Double base smokeless powder contains :
Answer: B
Double base smokeless powder contains nitrocellulose and nitroglycerine.
Single base powder is nitrocellulose alone. Double base powder adds nitroglycerine, which raises the energy, and triple base powder adds nitroguanidine as well. These smokeless propellants replaced black powder in modern ammunition.
Potassium chlorate and arsenic or antimony sulphides are ingredients of primer and pyrotechnic mixtures, not of smokeless propellant, and potassium chloride is not an explosive ingredient.
