急ぎなんですけど、問7からの考え方がうまくはまりません。ただ公式に当てはめてるだけだったりしてて理解できてないんですけど解説含めて教えてください 問7から問11です。一問でもいいです

① 0.10mol/Lの酢酸水溶液 50ml をとり、0.10mol/Lの水酸化ナトリウム水溶液を滴下 したところ、図に示すような中和滴定曲線が得られた。 酢酸の電離定数 Ka を 2.0× 10mol/L, 水のイオン積 Kw を 1.0×10" (mol/L)', log2=0.30, log3=0.48 「2=1.4と して、次の各問い (問1~9) に答えよ。 pH 1 酢酸水溶液中で成立している電離平衡を式で答えよ。 問2 酢酸の電離定数 Ka を表わす定義式を答えよ D点 C点 (3) 7B-B-点 A点 09 問3 酢酸の電離度を求めよ。 0 滴下量 問4 滴定前のA点のpHを少数第1位まで求めよ。 2530 50 100 mL (4) 問5 B 点では,酢酸と酢酸ナトリウムが等量ずつ混合しており、酸や塩基を加えて pHがほぼ一定に保たれる働きを持つ溶液になっている。 このような溶液を何 というか。 問6 B点のpHを少数1位まで求めよ。 → pka p #和点 2 問7 点のpHを少数1位まで求めよ。 →PH= platosaedathcool]=[ctocod].5 HAI 問8 C 点の pH を少数 1位まで求めよ。 kp kw = ・kaVkbe 問9 D点のpHを少数1位まで求めよ。 問10 B点の溶液に 1.0mol/Lの塩酸水溶液 5mL を加えた。 このときのpHを少数1 位まで求めよ。 15 問11 B 点の溶液に 1.0mol/Lの水酸化ナトリウム水溶液 0.5mL を加えた。このとき のpHを少数1位まで求めよ。 CH3COONa (0,10 mol/L) 10~100ml CH3COOH (0.10mol/L)
