Show also that the stoichiometry of these silicates becomes (SiO3)n2n-.
Double chain silicates are called amphiboles. What is the stoichiometry for the type of double chain silicates shown in Inorganic Chemistry by Swaddle (a diagram is also shown on the web site)?
What mineral is the most commonly sold asbestos? Describe its structure feature.
What are the concerns in applications of asbestos?
An effective operation is to have 67% of the sodium ions replaced by calcium ion in a water softener. How much water shall be allowed to pass the water softener between regenerations of the zeolite A?
If, on average, 25.0% of the sodium ions from a 6.0-M NaCl solution replace the calcium ions in the zeolite during the regenration process, how much 6.0-M NaCl solution should be used each time for the regeneration of the zeolite in the water softener? Assume that all the calcium ions are replaced by sodium ions.
