Web第四单元沉淀溶解平衡第二课时作业1下列化学原理的应用,主要用沉淀溶解平衡原理来解释的是AlOH3具有两性误将钡盐BaCl2BaNO32当作食盐食用后,常用0.5的Na2SO4溶液解毒蛋壳能溶于食醋碳酸钡不能作钡餐而硫酸钡能ABC D2在pH_文件跳动filedance.cn WebKsp is called the solubility product constant or, more simply, the equilibrium constant. of a slightly soluble ionic compound. The small Ksp value for BaSO4, 1.5x10-9, means that in pure water the molar concentration of Ba+2 equals the molar concentration of SO4-2 and each equals 3.9 x10-5 mol/L as shown below: Ksp = [Ba+2][SO4-2] = 1.5x10-9

Webksp 与qi 的意义: ksp表示难溶电解质沉淀溶解平衡时饱和溶液中离 子浓度的乘积。在一定温度下ksp为一常数。 qi则表示任何情况下离子浓度的乘积,其值不定。 溶度积规则: qi>ksp时,溶液为过饱和溶液,沉淀析出。 qi=ksp时,溶液为饱和溶液,处于平衡状态 。 WebThe K sp of Ag 2CrO 4,AgCl,AgBr and Agl are respectively, 1.1×10 −12,1.8×10 −10,5.0× 10 −13,8.3×10 −17.

Web12. Contoh soal dan pembahasan hasil kali kelarutan (Ksp) 1. Sebanyak 0,7 gram BaF2 (Mr = 175) melarut dalam air murni membentuk 2 L larutan jenuh. tentukan Ksp dari BaF2. Pembahasan Jumlah mol dari BaF2 adalah: n = 0,7 / 175 = 4 × 10−3 mol Kelarutannya adalah S = 4 × 10−3 mol / 2 L = 2 × 10−3 mol/L Web16 nov. 2024 · Ksp = [Ag +] 2 [CrO 42-] The common ion would be CrO 42- since you have 1.20 M potassium chromate (K 2 CrO 4 ). Because the [CrO 42-] is so large from the potassium chromate (1.2 M) we can ignore the [CrO 42-] contributed by the Ag 2 CrO 4 as it will be very small. Now we can write the Ksp expression as follows: Ksp = [Ag +] 2 [1.2 M] Web3 apr. 2024 · K s p = [ A g +] 2 [ C r O 4 2 −] Note: The solubility product of silver chromate is very low and therefore even at low concentration of the ions in water, the product of … malala aboriginal health service
