Porosity of filter paper
WebJun 17, 2008 · Most filter paper has a texture to it and any solid placed on it during the weighing may stick to the surface and not be transferred quantitatively to a vessel of choice. ... Because of the porosity of the filter paper some of the CaC2O4 x H2O precipitate passes through the filter paper. WebPorosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%. Strictly speaking, some tests measure the "accessible void", the total amount of void space accessible from the surface (cf. closed-cell foam).
