2 5 つのビーカー ビーBa↑、うすい硫酸を50cmずつ入れた。A~Eに、うすい 水酸化バリウム水溶液を、 Aには10cm、Bには20cm Cには30cmDには 40cmEには50cm加えると、A~E のそれぞれで白色沈殿が生じた。 生じた 白色沈殿をろ過してよく乾燥させ、質量を測定した。 右の図は、 A~Eについて、 加えたうすい水酸化バリウム水溶液の体積と生じた白色沈殿の質量との関係をグ ラフにまとめたものである。 次の問いに答えなさい。 H2SO4 Ba(OH)2 (1) 生じた白色沈殿は何か。 化学式で答えなさい。 1.00 色 0.80 0.60 白色沈殿の質量 g 0.40 0.20 (g) 0 うすい水酸化バリウム 水溶液の体積 〔cm²〕 10 20 30 40 [BaSO4 □(2) ビーカーC、D、Eで生じた白い沈殿の質量が同じである理由を、簡単に書きなさい。 水酸化バリウムをふやしてもこれ以上中和できる水素イオンがないから □ (3)十分に反応させたあとの5つのビーカーの中で、 水溶液中に存在する硫酸イオンとバリウムイオンの 数が最も少ないものはどれか。 A 〜E から1つ選びなさい。 中性だから! [C 新たに用意したビーカーFに、実験で用いたうすい硫酸20cmとうすい水酸化バリウム水溶液 15cr を入れ、十分に反応させた。このとき生じる白い沈殿の質量は何gか。
