A white mixture of sucrose and sodium bicarbonate will eventually turn black and the snake will grow about 15–50 centimetres (5.9–19.7 in) long after it is lit. [4] Three chemical reactions occur when the snake is lit. Sodium bicarbonate breaks down into sodium carbonate, water vapor, and carbon dioxide: [2] 2 NaHCO 3 (s) → Na 2 CO 3 (s ...
Sodium bicarbonate (IUPAC name: sodium hydrogencarbonate [9]), commonly known as baking soda or bicarbonate of soda, is a chemical compound with the formula NaHCO 3. It is a salt composed of a sodium cation (Na +) and a bicarbonate anion (HCO 3 −). Sodium bicarbonate is a white solid that is crystalline but often appears as a
Bath bombs on display in a Lush cosmetics shop. A bath bomb or bath fizzie is a toiletry item used in the bath. It was invented and patented in 1989 by Mo Constantine, co-founder of Lush Cosmetics. [1] It is a compacted mixture of wet and dry ingredients molded into any of several shapes and then dried.
Natron is a naturally occurring mixture of sodium carbonate decahydrate (Na 2 CO 3 ·10H 2 O, a kind of soda ash) and around 17% sodium bicarbonate (also called baking soda, NaHCO 3) along with small quantities of sodium chloride and sodium sulfate. Natron is white to colourless when pure, varying to gray or yellow with impurities.
Another formula consists of indigo carmine, ascorbic acid , sodium bicarbonate, sodium chloride, copper(II) sulfate, sodium hydroxide and water. [17] By doing so, chemical waste and the level of corrosive chemicals is reduced. The amount of solid chemicals dissolved in the experiment could be reduced from 60 grams to 6 grams.
The false claim that a 14-year-old student built an atomic bomb as a science project originates from a satirical website.
A bicarbonate salt forms when a positively charged ion attaches to the negatively charged oxygen atoms of the ion, forming an ionic compound. Many bicarbonates are soluble in water at standard temperature and pressure; in particular, sodium bicarbonate contributes to total dissolved solids, a common parameter for assessing water quality.

Smoke with a suitable composition can be used as a fire suppression agent.A pyrotechnic composition similar to black powder, composed of 15% charcoal and 85% potassium nitrate, generates thick smoke composed of particles of mainly potassium carbonate, which has fire extinguishing properties.
