is soluble in water, insoluble in acetone, ethanol and ether, slightly soluble in acid, sulfuric acid. Crystallization from aqueous solution of barium chloride often contains two crystal water. When heated to 113℃, it loses crystal water and becomes anhydrous barium chloride, it is white powder...
Another method which i am considering that treating impure barium chloride with sulfuric acid but i think it will make barium sulphate which can't convert back to barium chloride . So it would be great if there any method which can remove impurity of Nacl from barium chloride.. ...
the invention relates to a process for obtaining barium sulphate used in medical, pharmaceutical, by introducing a solution of barium chloride in sulfuric acid.in stoichiometric ratio, by stirring and heating, after which they do laundry with demineralized water, by stirring - settling - siphoning,...
Bmschem main products: barium hydroxide, barium chloride, barium sulfate, strontium nitrate, barium acetate, barium nitrate, strontium chloride, strontium carbonate, manganese chloride, barium carbonate, witherite, barite, etc. We are specialized in the
also be used as a white pigment and an administrated agent upon stomach X-ray angiography; it can also used as copper flux, drilling mud weight enlarging agent and the filling agent of rubber, paper, and plastic. It is produced from the reaction between sulfuric acid and barium chloride. ...
mainly comprising barium salt; filtrate is extracted to react with a small amount of barium sulfate to recover chlorine ions so as to obtainbarium chloride subject to complete reaction; and finally the barium chloride and sulfuric acid react with each other to obtain the precipitated barium sulfate...
chloride⎯dissolve 0.30 g of barbital in 20 ml of acetone and add 6 ml of dilute nitric acid and water to make 50 ml. perform the test using this solution as the test solution. prepare the control solution as follows: take 0.30 ml of 0.01 mol/l hydrochloric acid vs, 20 ml of ...

chlorides which mainly contain barium salt, the filtered clear liquid reacts with little amount of the barium sulfate to recover chloride radicals so as to obtain barium chloride after complete reaction, and finally the barium chloride reacts with sulfuric acid to obtain the precipitated barium ...
(BaCO3) is the inorganic compound precipitated from a solution of barium hydroxide and urea. Barite is majorly used to manufacture barium carbonate. BaCO3 is white in color and generally available in powder form. It is insoluble in water and soluble in a majority of acids except sulfuric acid....
