故答案为:A12O3、SiO2; (2)在草酸钛钾[K2TiO(C2O4)2]中K为+1价,C2O42﹣为﹣2价,O为﹣2价,设钛元素的化合价是x,化合物中元素化合价代数和为0,+1×2+x=﹣2+(﹣2)×2,x=+4,所以钛元素的化合价是+4, 故答案为:+4; (3)将钛铁矿溶于氢氧化钠溶液过滤,滤渣中主要为FeTiO3,还有...
Al2O3+2NaOH=2NaAlO2+H2O,滤渣中主要为FeTiO3,还有少量Fe2O3, 故答案为:A12O3、SiO2; (2)在草酸钛钾[K2TiO(C2O4)2]中K为+1价,C2O42-为-2价,O为-2价,设钛元素的化合价是x,化合物中元素化合价代数和为0,+1×2+x=-2+(-2)×2,x=+4,所以钛元素的化合价是+4, 故答案为:+4;...
