ヘンダーソン・ハッセルバルヒの式を用いる問題です。 (4ー2)と(4ー3)がわからないので教えてください。 わかりやすく説明していただけると助かります

酢酸緩衝液の理論的な pH 値は、次式 (一般に、 Henderson-Haselbalch で計算できる。 equaton: ヘンダーソン・ハッセルバルクの式と呼ばれる) でき にで [cg.COO7] p = KK。- [czcoo] 2 ただし、 pKa : 酢酸の本解離定数 [CHJCOOH] : 酢酸の濃度 [CH。COO] : 酢酸ナトリウムの濃度 (4-1) 酢酸の水溶液中における化学平衡を考慮して、 上記の式を誘導 しなさい。 (ヒント :酢酸の水溶液中における解離は次式で示され 、 る。この式から平衡定数を導き、上の式と同じくなるように、両 辺の対数をとる。) CFPiCO0ガ7 + 万O キーー 7のO* + Cp、COO- (4-2) ヘングーツン・ハッセルバルクの式を用いて、0.10 M 酢酸沙 答液 10 mL と 0.10 M 酢酸ナトリウム水溶液 10 mL を混合し て得られる酢酸緩衝液の pH 値を求めぶさい、また、 その値と本 実験で得られた実測値を比較しなさい、。 (4-3) (4-2) の酢酸緩衝液に、 0.10 M 水酸化ナトリウム水溶渡を 1.0 mL、 3.0 mL、 5.0 mL 加えたときに得られる pH の理論値をへ 9リルイリ ンダーソツン・ハヘッセルバルクの式を用いて計算 し、本実験で得ら れた実測値と比較しなさい。 16
