The term chromic acid is usually used for a mixture made by adding concentrated sulfuric acid to a dichromate which may contain a variety of compounds including solid chromium trioxideThis kind of chromic acid may be used as a cleaning mixture for glass. Chromic anhydride in glacial acetic acid is used for the conversion of secondary alcohol to ketone.
Point out important. Chromic acid may also refer to the molecular species H 2 CrO 4 of which the trioxide is the anhydrideChromic acid features. It is also known as isopentyl alcohol isopentanol or in the IUPAC recommended nomenclature 3-methyl-butan-1-olAn obsolete name for it was isobutyl carbinol.

Mixture means any combination of two or more elements andor compounds in solid liquid or gaseous form except where such substances have undergone a chemical reaction so as to become inseparable by physical means.
3Ms bright matched component inks and films carry a 10 year warranty. LDPE is defined by a density range of 09100940 gcm3. Hence option 3 is the answer.
Inorganic oxidizer chemically cleans glassware. In a human radio-labelled drug study about 93 of the total dose was excreted in the urine within 48 hours. Concentrated nitric acid 68 - 70 is a transparent colorless or yellowish fuming suffocating hygroscopic corrosive liquidThis chemical attacks almost all metals.
Check the chemical compatibility of LDPE low density polyethylene with various chemicals solvents alcohols and other products.
