Answer (1 of 7): These answers don't really answer the question as to why it dimerises at all. Hg2+ is very stable due to the noble gas electron configuration (a filled valence 5d shell). Hg+ on the other hand has a 5d10 6s1 configuration. You can imagine how desperate it is to lose that s elect.. By simplification of the above equation, i = 0.8 ( 2) + 1 ⇒ i = 2.6. Thus, the Van't Hoff factor of H g 2 C l 2 in aqueous solution will be 2.6 . Note: Generally, the Van't Hoff factor is the representation of the number of ions that were dissociated in the presence of an aqueous solution. For some salts like mercury chloride, the ionisation. 氯化汞,俗称升汞,是一种无机物,化学式为HgCl2,呈白色结晶性粉末、有剧毒,溶于水、乙醇、乙醚、甲醇、丙酮、乙酸乙酯,不溶于二硫化碳、吡啶。氯化汞可用于木材和解剖标本的保存、皮革鞣制和钢铁镂蚀,是分析化学的重要试剂,还可做消毒剂和防腐剂 氯化亚汞亦称甘汞,是一种无机物,化学式为Hg2Cl2,分子量为 472.09,白色晶体或粉末。比重7.15,熔点为400ºC。由硝酸亚汞溶液中加入稀盐酸或由氯化汞与汞共热而成。不溶于水、乙醇、乙醚,微溶于盐酸,溶于王水、硝酸汞溶液、苯和吡啶。遇氨色变黑,长期见光会缓慢析出金属汞而变黑

Is Hg2Cl2 Soluble or Insoluble in Water? What about HgCl2

Sn (OH)2 + H+ reacts with OH- to form H2O making it more possible in an acidic solution than in pure water. Adding CuBr to H+ forms a weak acid HBr; thus, it is highly soluble in acidic solutions than pure water. Ag2SO4 + H+ form HSO4- with a K2 for H2SO4. In H2SO4. No K1 because it is a strong acid the first H explains its solubility in acidic. The Relationship Between K sp And the Solubility of a Salt . K sp is called the solubility product because it is literally the product of the solubilities of the ions in moles per liter. The solubility product of a salt can therefore be calculated from its solubility, or vice versa.
