NH2ONH2+NaC1O+2NaOH→N2H4?H20+NaC1+Na2CO3氨法以氨水及次氯酸钠为原料。氨水中加入0.1%骨胶,以抑制肼的过度分解。将次氯酸钠按氨与次氯酸钠摩尔比值为(50～60):1,迅速加人氨水中,在强烈搅拌下在常压或高压下进行氧化反应,先生成氯胺,后继续反应生成肼。反应液经蒸馏回收氨,再经真空蒸馏除去氯化钠及氢氧化钠,...
NaNO2 - NaCl - HCl - Ba(NO2)2I just used common ion effect for A - C & D and got it right.I just assumed this was asking a similar thing? Logged student8607 Full Member Posts: 227 Mole Snacks: +2/-3 Re: Common Ion Effect « Reply #3 on: March 12, 2009, 11:22:32 ...
The smoothed values were obtained from a least-squares regression of the experi- mental values to an equation of the form s = C a t 0 where S is the solubility in grams of NaCl per 100 g of saturated solution (g/lOO g), and tis the temperature in degrees Celsius. The coefficients,...
