1.分割想像化抽象为具体已知T℃时,某物质的不饱和溶液ag中含有溶质a’g,若溶液蒸发bg水并恢复到T℃时,析出溶质b’g,若溶液蒸发cg水,并恢复到T℃时,则析出溶质c’g,用S表示该物质在T℃时的溶解度,下式中正确的是:A.S=100a’/(a-a’)B.S=100(b’-c’)/(b-c)C.S=100c’/c D.S=100(b’-c’)
1. Segmentation Imagination abstraction is specifically known as T°C. The unsaturated solution ag of a substance contains a solute a’g. If the solution evaporates bg water and returns to T°C, the solute b’g will precipitate, if the solution evaporates cg. When water returns to T°C, the solute c’g is precipitated, and the solubility of the substance at T°C is represented by S. The correct formula is: AS=100a’/(a-a’)BS=100 ( B’-c’)/(bc)CS=100c’/c DS=100(b’-c’)
