この問題を解く方法を細かく教えていただきたいです。 よろしくお願いします。

実験の過程で生じた pH5.0 の廃水があり,その中に酢酸とピリジン(Py)が 全濃度で共に 0.03 M 含まれていることがわかった。この廃水における遊離 の(AcoH]と(HPy7を求めよ。

pHの計算についてです。 【写真一枚目】 0.1mol/Lの硫酸水溶液のpHを求めよ。 【写真二枚目】 0.1mol/Lの水酸化ナトリウム水溶液のpHを求めよ。 2問とも強酸、強塩基ですが写真 2枚目はなぜ近似した解き方。（高校で習ったように[OH^-]を求めてpHを... Read More

[解法] 1) [H*] を計算する。 2) -logo [H+] を求める。 ステップ1 H,SO.も強酸なので, 完全に解雑す ると考えることができる。しかし,これは二塩酸 であり,一つの H.SO、が解離すると2個のH*が 生成することに注意しなくてはならない。 HaSO4→ 2H* (a) + SO(a) 0.1 M H.SO。は, したがって[H*]=0.1×2=0.2 Mを与える。 ステップ2 ー1ogio0.2=約0.7 したがって, 0.1M H.SO, 溶液の pH=0.7
