Results for 'Sn':
EXPERIMENT 1 --------------- Platinum (II) gives a highly coloured compound with tin (II), it is not reduced to metallic platinum.
EXPERIMENT 2 --------------- Platinum(II) is not reduced by sulfide in acidic environments. When it is treated with stannous ions at the same time, then a dark brown compound is formed, but probably this is not metallic platinum but stannous sulfide. What speaks against this is that stannous chloride does not precipitate with H2S in acidic environments (see sequence 2), while with the Pt-compound a dark brown compound is formed. More research will be needed to resolve this.
EXPERIMENT 3 --------------- Palladium probably gives a very finely divided metallic compound, when it is reduced by stannous chloride. The intense colors, appearing in this experiment probably are caused by colloidal solutions.
EXPERIMENT 4 --------------- Tin (II) compounds forms either a yellow or orange/red compound with iodides. What compound is formed, depends on the concentration of the reactants. At very low pH such a compound is not formed anymore, and once formed, it can be dissolved.
EXPERIMENT 5 --------------- Dichromate is quickly reduced by tin (II) ions. Hydrogen peroxide does not show a visible reaction with tin (II) ions.
EXPERIMENT 6 --------------- Tin metal does not dissolve quickly in concentrated hydrochloric acid. Tin metal only slowly dissolves in aqua regia. The solution obtained is clear.
EXPERIMENT 7 --------------- Arsenic in oxidation state +5 is not easily reduced to elemental arsenic, except by tin(II) chloride.
EXPERIMENT 8 --------------- Arsenic in oxidation state +3 is quickly reduced to elemental arsenic by tin(II) chloride in hydrochloric acid.
