水のイオン積の単位はなぜ二乗されているのですか？ 添付画像にある説明からは、Kwは水の電離定数であり、すなわち平衡定数であることがわかります。 このことから、Kw=[H+][OH-]/[H2O]が本来の式の形であり、[H2O]≒1より[H2O]を省略して、Kw=[H+]... Read More

B 水のイオン積とpH 水の電離 水H2O はわずかに電離して、水素イオンH+と水酸化物 イオン OHを生じ,電離平衡の状態になっている。 H2O ←H+ + OH-] (27) ここで, 水の電離はごくわずかであり、水はほぼ純粋な溶媒とみなせる。 したがって水の濃度 [H2O] は一定と考えてよいので, 水の電離定数Kを 改めて Kw と表すと,次式のようになる。 これを水のイオン積といい, 温度一定のとき一定の値を示す。 ion product of water Kw=[H+][OH-] (28) 中性の水では, H+ と OH の物質量は等しく, また, 25℃において, [H+]=[OH-]=1.0×10mol/L となるので,次式が成り立つ。 Kw=[H+][OH-]=1.0×10-14 (mol/L)2 (25℃) A W p.60② 一般に,酸性や塩基性の希薄溶液でも式 (29)が成立し, Kw は一定値を示 す。例えば,式 (27) で,水に酸を加えて [H+] が増加すると,平衡は左に移 動して [OH-] は減少する。 また, 水に塩基を加えて [OH-]が増加する と,平衡は左に移動して [H+] は減少する。 (29)
