①はどうして硫酸のPHは同じ濃度の塩酸のPHより大きくないのですか?硫酸が2価であるのは関係がないということですか?教えてください🙏

36 酸塩基のpH 水溶液のpHに関する記述 ①~⑤のうち、正しいものを一つ選べ。 ① 0.010mol/Lの硫酸のpHは,同じ濃度の塩酸のpHより大きい。 ② 0.10mol/Lの酢酸のpHは、同じ濃度の塩酸のpHより大きい。 3 0.10mol/Lのアンモニア水溶液のpHは、同じ濃度の水酸化ナトリウム水溶液のpHより 大きい。 (4) pH3の塩酸を10倍に薄めると,溶液のpHは8になる。 36 例47 146 解答 5 pH 10 の水酸化カリウム水溶液を100倍に薄めると,溶液のpHは12になる。 -00-00 た pH 小 大 03-01 R0,00 H 反比例 [OH] 小 [H+] 大 小 HCA ③ 大 © 店の H2SO4 → 2H+ + SO2- →2H++ [H+] = 0.020mol/L 100m HCI- → H+ + Cl¯ [H+] = 0.010mol/L pH = 10 なら [H+] = 10mol/L [H+] [OH-] = 10-14 (mol/L) 2より, 酢酸の [H+] < 0.10mol/L ※酢酸は弱酸 塩酸の [H+] = 0.10mol/L E.I [OH-] = 10^*mol/L 08.0 これを100倍に薄めると ③ アンモニアの [OH-] < 0.10mol/L CH [OH-] = 10-4 ※アンモニアは弱塩基 水酸化ナトリウムの [OH-] = 0.10mol/L 100 Tom A ② 計算上は [H+] = 10-3 × 1 = =10mol/Lであるが =10mol/LpH = 8CHM lom\g18 え お 薄めることによって,pHが7を超えて酸性→塩 基性,塩基性→酸性に変化することはない。 105 lom 2S0.0 10m 250.0 lom\g A 薄めるために加える水のpHは7 [H+] = 10^7mol/L) したがって,pHが7を超えることはない。
