11. The chemical precipitation of poorly soluble salts is not included in the computation method. 12. The bottom ash is washed to eliminate soluble salts . 13. Also, high concentrations of soluble salts or metals can limit the use of land spreading. 14. They grow well in water containing up to 3.0 to 4.0 % of soluble salts . 15. All water-soluble salts and mixtures have characteristic critical humidities; it is a unique material property. 16. The method remains the primary and most flexible test method for soluble salts on metal surfaces. 17. The effects of soluble salts , biodegradation, and desiccation that cause further deterioration of artifacts are controlled. 18. In 1891 G . Merling obtained a water-soluble salt from a reaction of cycloheptatriene and bromine. 19. Clay minerals in the A horizon decompose by reaction with humic acids and form soluble salts . 20. Ingested Low-fired oxides and soluble salts such as nitrate can be absorbed into the blood stream.
