To produce pure tin metal from this sort of tin ore, the ore usually is heated with coal (carbon). In contrast, reactions of acids with bases in water involve proton (H+) transfer from an acid to a base. According to the Arrhenius theory, acid-base reactions involve the combination of the hydrogen ion (H+) and the hydroxide ion to form water. An exchange reaction will occur whenever a predicted product is not soluble in water. [4], Oldhamite is the name for mineralogical form of CaS. 10 So far, we have always indicated whether a reaction will occur when solutions are mixed and, if so, what products will form. To obtain the complete ionic equation, we write each soluble reactant and product in dissociated form: \[ \ce{3Ba^{2+}(aq)} + \cancel{\ce{6NO_3^{-}(aq)}} + \cancel{\ce{6Na^{+} (aq)}} + \ce{2PO_4^{3-} (aq)} \rightarrow \ce{Ba_3(PO_4)_2(s)} + \cancel{\ce{6Na^+(aq)}} + \cancel{\ce{6NO_3^{-}(aq)}} \nonumber \].
