化学 高校生

化学のモル質量などの問題でこのようにイオンを使う時と使わないときの見分け方を教えて欲しいです!!

101 硫酸 0.0100mol, 塩化水素 0.0200mol 硫酸と塩酸の混合溶液 H+ CI SO 存在 HCl → H+ + CI- HzSO → 2H++ SO- 塩化バリウム水溶液 Ba', Cl' が存在 BaCl → Ba2+ + 2CI- 硝酸銀水溶液 Ag+,NOが存在 AgNO3 → Ag+ + NO3- SOを含む水溶液にBa' を加えると, BaSO (式量233) の沈殿が生じる。 2.33g 沈殿した BaSO2.33gは =0.0100mol で, 加えた Back は 233 g/mol 0.0200mol であるから, Baが溶液中に残っていて, SO はすべて沈 殿したとわかる。したがって, はじめの混合溶液に含まれていた SO すなわち H2SOは 0.0100mol Ba²+ + SO- (反応前) 変化量) (反応後) 0.0200 -0.0100 0.0100 BaSO& 0.0100 0 (mol) -0.0100 +0.0100 (mol) 0 0.0100 (mol) CI を含む水溶液に Ag+ を加えると, AgCl (式量 143.5) の沈殿が生じる。 8.61 g 沈殿した AgCl8.61gは -0.0600mol で,加えた AgNO3 143.5g/mol は 0.0800 mol であるから,Ag* が溶液中に残っていて, CI- はすべて沈 殿したとわかる。 したがって, 硝酸銀水溶液を加える前に含まれて CIは 0.0600mol である。 Ag+ + CI - AgCl (反応前) 0.0800 0.0600 (変化量) -0.0600 -0.0600 0 +0.0600 (mol) (mol) (反応後) 0.0200 0 0.0600 (mol) このうち 0.0200molx2=0.0400mol は BaClz として加えられたもの であるから, はじめの混合溶液に含まれていたHC1は, 0.0600mol-0.0400mol=0.0200mol MO 101 混合物の定量 硫酸と塩酸の混合溶液がある。これに0.0200 melの塩化バ リウムを含む水溶液を加えたところ, 硫酸バリウムの沈殿 2.33g が生した。 この沈殿を 除いたろ液に 0.0800molの硝酸銀を含む水溶液を加えたところ、塩化銀の沈殿8.61g| [神戸学院大 改] が生じた。 最初の混合溶液中の硫酸と塩化水素はそれぞれ何molか。
