金属与酸反应的常用规律(The common law of the reaction between metal and acid) The common law of the reaction between metal and acid 1. the reaction of metals with acids is a redox reaction, and the amount of metal that loses electrons is equal to the amount of material that acids yield...
Metallic titanium is dissolved in an aqueous solution of telluric acid, the liquor evaporated, preferably at temperatures below 78 DEG C., to produce a sludge, the sludge dried to form a powder, and the latter heated to 800--1700 DEG C., the resultant product being cooled out of contact...
