A flowchart is a visual representation of the sequence of steps and decisions needed to perform a process. Each step in the sequence is noted within a diagram shape. Steps are linked by connecting lines and directional arrows. This allows anyone to view the flowchart and logically follow the process from beginning to end.

In 1863, Ernest Solvay invented a radically new industrial process for the production of soda ash. His technological breakthrough, known as the Solvay process or ammonia-soda process, provided a more efficient and cleaner alternative to the Leblanc process it replaced. By 1900, Solvay's innovation was so successful that it was used to produce ...

Principle. ↪ When carbon dioxide gas is bubbled into pure brine solution saturated with ammonia, ammonium bicarbonate is formed in cold which reacts immediately with sodium chloride to form sodium bicarbonate and ammonium chloride. NH 3 + H 2 O + CO 2 → NH 4 HCO 3. NH 4 HCO 3 + NaCl → NaHCO 3 + NH4Cl.
