Tungstic acid salts

Blood should be deproteinized by some technique which leaves no extra salt, acid, or alkali in the supernatant Some suitable techniques are with tungstic acid, with ethanol (BIO), or with zinc sulphate and barium hydroxide (S21). The supernatant is desalted in the same way as urine and, if necessary, concentrated before applying to the paper. Subsequent technique is as for urine.

Salts of Molybdic and Tungstic Acids. What types of salts of molybdic and tungstic acids exist Give examples of isopoly- and heteropoly molybdenum and tungsten compounds. What is the composition of para- and metamolybdates and of para- and metatungstates Which molybdates and tungstates dissolve poorly in water ... 

Of special interest are olefm epoxidation with peroxy acids at the moment of their formation from acid anhydrides and hydrogen peroxide. Among the catalysts of olefin oxide formation from olefins interacting with H202 in the presence of metal (Ti, W, V, Ta, Ge, Mo, U, Ru) oxides or acids are tungstic acid and its salts [47], Epoxidation is described by the following mechanism ...
