Ammonium chloride will tend to react with sodium hydroxide to form ammonia, water, and sodium chloride. NH4Cl + NaOH --> H2O + NH3 + NaCl The net ionic equation is NH4+ + OH- --> NH3 + H2OThe resulting solution is basic because of the dissolved hydroxide. The reaction is exothermic, but the reaction is slower than that of sodium (immediately below lithium in the periodic table). As the reaction continues, the concentration of the hydroxide increases. 2Li (s) + 2H 2 O → 2LiOH (aq) + H 2 (g)

ionic compound. The sum of the ionic charges in the formula is always zero, which indicates that the total number of positive charges is equal to the total number of negative charges. For example, the +1 charge on the sodium ion is cancelled by the –1 charge on the chloride ion, to form a net zero charge. The following tests for the following cations are fully described including explanations, methods, observations and equations, so described are how to test for positive ions – mainly metal ions: ammonium ion NH 4 +, hydrogen ion/oxonium ion/acids H + /H 3 O +, lithium ion Li +, sodium ion Na +, potassium ion K +, calcium ion Ca 2+, strontium ...

Mar 04, 2008 · Although this equation looks similar to the ionization of HCl, the remarkable difference is the shapes of the arrows representing the equations. -----> represents the complete ionization <----> represents the partial ionization (equilibrium reaction) TCC’s Ammonium Bromide, NH4Br, is the ammonium salt of hydrobromic acid. The chemical crystallizes into colorless prisms, possessing a saline taste. It sublimes on heating and is easily soluble in water. On exposure to air it gradually assumes a yellow color because of the oxidation of traces of bromide (Br–) to bromine (Br2). Ammonium bromide is used for photography in films, plates and ...
