==chemical properties==tin(ii) chloride can dissolve in less than its own mass of water without apparent decomposition, but as the solution is diluted hydrolysis occurs to form an insoluble basic salt::sncl2 (aq) + h2o (l) sn(oh)cl (s) + hcl (aq)therefore if clear solutions of tin(ii) chloride are to be used, it must be dissolved in hydrochloric acid (typically of the same or greater molarity as the stannous chloride) to maintain the equilibrium towards the left-hand side (using le chatelier's principle).
