Smoke screens are used in warfare for the purpose of concealment and camouflage. They generally consist of fine particles of titanium oxide dispersed in air. These particles scatter light, making it difficult to see through the smoke. Smoke screens can also be used to create a false target or to obscure the movement of troops.<\/p>\n<p>(a) Sodium chloride is table salt.
