（轉(zhuǎn)自/）兩溶液等積混合求溶液pH的：兩種強酸溶液，或兩種強堿溶液，或一種強酸溶液與一種強堿溶液等體積混合，當(dāng)兩溶液的pH值之和為14時，混合液pH＝7；當(dāng)兩溶液的pH值之和小于13時，混合液的pH值為原pH值小的加上；當(dāng)兩溶液的pH值之和大于15時，混合液的pH值為原pH值大的減去。若用pHA、pHB、pHC分別表示兩種溶液及混合液的pH值，且pHA＜pHB，當(dāng)pHA＋pHB＝14時，pHC＝7；當(dāng)pHA＋pHB＜13時，則pHC＝pHA＋；當(dāng)pHA＋pHB＞15時，則pHC＝pHB－。，或者說，弱者是強者的陪襯。由于溶液的體積增加一倍，溶液的[H+]或[OH－]除2，。因此，pH＝2的鹽酸與pH＝6的鹽酸等體積混合，或與pH＝10的NaOH溶液等體積混合，以及用水稀釋一倍，其結(jié)果都一樣，pH值都是。。因為兩種強酸或兩種強堿溶液等體積混合時，若pH值相差1，混合液的pH值應(yīng)是±；強酸、強堿混合，pH值與pOH值相差1(即pH值之合為13或15)，應(yīng)是±；若以上相差值小于1，誤差就更大。另外，這一規(guī)律只適用于強酸、強堿，不適用于弱酸合弱堿；是等體積混合，而非不等體積混合。例1．(MCE81)pH＝5合pH＝3的兩種鹽酸，以等體積混合后，溶液的pH值是()：B。例2．pH＝2的鹽酸合pH＝12的NaOH溶液等體積混合后，溶液的pH值是()：B。便攜式和臺式pH計測量范圍較廣，常用儀器，不同點是便攜式采用直流供電，可攜帶到現(xiàn)場。</p><div
