11. The silicates are essentially insoluble in all polar solvent except methanol. 12. Its complexes also tend to be highly soluble in non-polar solvents . 13. It exists as a colourless solid that is soluble in polar solvents including water. 14. Polar solvents are combustible liquids that destroy conventional fire-fighting foam.15. In the iodine / polar solvents promote ion dissociation and hence increase molar mass. 16. However, intercalation of polar solvents occurs significantly different in Brodie and Hummers graphite oxides. 17. This is the same for a very polar chemical and a very non-polar solvent . 18. Its stability can be attributed to its insolubility in both polar and non-polar solvents . 19. A tea will be rich in polar components because water is a polar solvent . 20. The foam is used at 3 % both on hydrocarbon and polar solvent fires.
