(4)がわかりません

第4間 文章を読み、問いに答えよ。 [Hs-) 確化水素は、水溶液中では式①,及び式ののように2段階で電離している。式の, ②の平衡定数をそ れぞれん、んとする。 HS * H* + HS K-9,0×10- mol/L K=1.2×10-15 mol/L 「HS] の IS + S 2) このとき、温度を一定に保ってpll を調整すると、電離平衡は移動する。ただし,硫化水素の水への 溶解度は、Hに関わらず常に 0.10 mol/L とする。 一方,金属Mの硫化物 MS の電離平衡は MS (固) * MP* + S- と示される。ここで,平衡定数は MS(固)の量に無関係なので Ksp= [f+] [S°-] と表され, f*と S°-の濃度の積が Kspを超えると MS が沈殿する。このとき、pH を変化させたときの水溶液の体積変化は無視できるものとする。 間1 下線部で、pHが 1.0のときの水素イオン濃度[Imol/L]を有効数字2桁で求めよ。 間2 「下線部で,Hを1.0にしたときの硫化物イオン濃度 mol/L]を有効数字2桁で求めよ。 Cu*を0.010(mol/L), Fe'+を 0.060 (mol/L)含むむ水溶液の pH を1.0に調整し、硫化水素を通 じて飽和させた。CuS, FeS の Ksp をそれぞれ 6,0×10~30,6.0×10-18 (mol/L)? とする。 (1)この条件において、沈殿する物質の化学式をすべて記せ。 沈殿する物質がない場合は、「なし」と答えよ。 (2)この条件における、溶液中のCuftの濃度[Imol/L]を有効数字2桁で求めよ。 (3)この条件における、溶液中の Fe'tの濃度[Imol/L]を有効数字2桁術で求めよ。 間3 Fe 間3の水溶液について、Fe" を沈北殿させるための plH の最小値を小数第2位まで求めよ。 ただし、1og1o2.0=0.30、logio3.0=0. 48 とする。 間4 12
