A process for separating and recovering paraffin sulphonic acids from mixtures with water and sulphuric acid is described, consisting of: bringing such a mixture into contact under extraction conditions with a saturated aliphatic or cycloaliphatic liquid hydrocarbon; separating an aqueous liquid phase ...
Sulphuric acid is diluted by mixing concentrated acid with water in the ratio acid :water=2 :25.It is then further diluted by adding water so that the ratio weak acid :water=1 :4.How much concentrated acid is needed to make 300mL of the final mixture.以上求高人翻译. 扫码下载作业帮拍照...

Concentrated sulphuric acid (95-98%) becomes corrosive to stainless steel when diluted between 20-80%. Corrosiveness is further enhanced when acid is diluted with sea water because of the high chloride content. When tank cleaning after discharge of a cargo of sulphuric acid, a large amount of ...
Using dilute solutions of TBP (1–5 per cent) in kerosene and in benzene (1 per cent), a maximum in the amount of water extracted from sulphuric acid solution is obtained at about 5 M H 2SO 4. This behaviour can be explained by assuming the following main reaction: TBP(org) + 2H ...

98% Sulphuric Acid (H2SO4) Good Quality Sulfuric Acid Product Description Sulfuric acid (alternative spelling sulphuric acid), also known as vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with molecular formula H2SO4. It is a colorless, odorless, and visc...
An agent (I) for the treatment of neurodermatitis, dandruff and similar conditions contains a mineral acid (pref. sulphuric acid) at pH 0-6 (pref. 0-2.5) and water and/or an alcohol. (I) pref. contains in aq. soln. 2-20 (esp. 7-10) ppm. Fe2+/Fe3+, 0.1-10 (esp. 1.5-4)...
This water layer showed resistance against further adsorption of water molecules and was very stable at room temperature. However, similar structure of water was not observed at heptane/silica interfaces. Water structures on mica were studied with atmospherically relevant sulphuric acid concentrations. ...
