anthropos Posted August 2, 2005 Share Posted August 2, 2005 My textbook states that I can deduce the type of acid used to make a salt by analysing its negative ions. Calcium Chloride - CaCl2-----Ca-base ion Cl2-acid ion so you know that by CaO + HCL --> CaCl2 + H2O Then I saw the following: Ammonium sulphate - (NH4)2 S04-----(NH4)-base ion SO4-acid ion 2NH3 + H2O + H2SO4 --> (NH4)2 SO4 +H2O Um...is the 2NH3 dissolved in H2O to give NH3 (aq) [aqueous ammonia] and then added to H2SO4 for neutralisation? I mean, the 2NH3 + H2O is actually mere dissolving but not neutralisation, right? Sorry, guys, I don't know how to write subscripts on the forum....so it is rather hard to see what I am writing. Thanks, Anthropos Link to comment Share on other sites More sharing options...
YT2095 Posted August 2, 2005 Share Posted August 2, 2005 the NH3(g) + H2O(l) "react" to make NH4OH(l) (ammonium Hyroxide) Link to comment Share on other sites More sharing options...

anthropos Posted August 2, 2005 Author Share Posted August 2, 2005 Oh...great!!! Thx, primarygun! Link to comment Share on other sites More sharing options...
latentheat Posted August 2, 2005 Share Posted August 2, 2005 Ya for subscripts you can either use latex OR use the subscript bb code... MnO[sub*]2[/sub] without the * gives MnO2. Superscripts can be done this way too... SO4[*sup]2+[/sup] without the * gives SO42+ Link to comment Share on other sites More sharing options...
