A正確。又由于溶液中，陰離子電荷總數(shù)與陽離子電荷總數(shù)相等，D也正確。本題應(yīng)選A、D。例6.將pH為6的鹽酸與pH為4的鹽酸等體積混合后，溶液中氫氧根離子濃度(mol/L)**接近()A.(10-8＋10-10)××10-10－5×＋10-10解析：按，混合液的pH＝，即pOH＝，山東PH計制作安裝。將各選項舍去[OH-]小的，山東PH計制作安裝，求pOH。＝－lg(5×10-9)＜9；B.；C.－lg(－5×10-5)，舍去；。應(yīng)選B。例7.把10mLpH＝10的強堿溶液小心地加入10mLpH＝4的某酸溶液中，在完全反應(yīng)后的溶液中滴入紫色的石蕊試液時，溶液顯紅色，山東PH計制作安裝，則此酸為()A.一元強酸B.二元強酸C.任何強酸D.弱酸解析：根據(jù)，若某酸為強酸，則混合液的pH值應(yīng)為7。故可排除A、B、C，因此應(yīng)選D。例8.等體積混合mol/L鹽酸合mol/LBa(OH)2溶液后，溶液的pH值等于()：堿中[OH-]＝mol/L，pH＞13，鹽酸中pH＝1，混合液的pH應(yīng)＞13－＞12，故應(yīng)選A。例＝2的鹽酸與pH＝13的NaOH溶液按體積比10∶1混合，混合液的pH值**接近于()：可將NaOH溶液體積增大10倍，使與酸溶液成等體積混合，這時堿溶液的pH＝12，由于2＋12＝14，故混合液pH＝7，應(yīng)選C。例10．4體積pH＝9的Ca(OH)2溶液與1體積pH＝13的NaOH溶液混合后，溶液中氫離子濃度為()×10-13mol/×10-12mol/LC.×(1×10-1＋4×10-5)mol/LD.。</p><div
