Fireworks take many forms to produce the four primary effects: noise, light, smoke, and floating materials (confetti for example). They may be designed to burn with colored flames and sparks including red, orange, yellow, green, blue, purple, and silver. Displays are common throughout
Barium acetate Barium acetate Barium acetate (Ba(CHO)) is the salt of barium(II) and acetic acid. Barium acetate is generally produced by the reaction of acetic acid with barium carbonate: The reaction is performed in solution and the barium acetate crystallizes out. Alternatively, barium sulfide can be used: Again, the solvent is evaporated off and the barium acetate crystallized. Barium acetate is a white powder, which is highly soluble: at 0 °C, 55.8 g of barium acetate can be dissolved in 100 g of water. It decomposes upon heating into barium carbonate. When heated in air, barium acetate decomposes to the carbonate. It
