Industrial Chemistry > The Solvay Process Has Been in Use Since The 1860s
The Solvay process has been in use since the 1860s
Students learn to:
- identify the raw materials used in the Solvay process and name the products
- describe the uses of sodium carbonate
- identify, given a flow chart, the sequence of steps used in the Solvay process and describe the chemistry involved in:
– brine purification
– hydrogen carbonate formation
– formation of sodium carbonate
– ammonia recovery - discuss environmental issues associated with the Solvay process and explain how these issues are addressed
Students:
- perform a first-hand investigation to assess risk factors and then carry out a chemical step involved in the Solvay process, identifying any difficulties associated with the laboratory modelling of the step
- process information to solve problems and quantitatively analyse the relative quantities of reactants and products in each step of the process
- use available evidence to determine the criteria used to locate a chemical industry using the Solvay process as an example
