Solutions of tin ( II ) chloride can also serve simply as a source of Sn 2 + ions, which can form other tin ( II ) compounds via precipitation reactions.

In both cases, the precipitation reaction rely on a quick transformation of acidic hydrolyzed iron ions into the spinel iron oxide structure, by hydrolysis at elevated pH values ( above ca . 10 ).

"' Liesegang rings "'( ) are a phenomenon seen in many, if not most, chemical systems undergoing a precipitation reaction, under certain conditions of concentration and in the absence of convection.
14.
Roughly speaking if Y is more negative than X ( that is, reaction 2 is more exothermic than reaction 1 ), then the substance will be " insoluble ", because thermodynamically the precipitation reaction is more likely than the solvation reaction.
15.
The serological characters represented as the antigenic determinants of CPsV-EG isolate related to monoclonal antibodies specific CPsV strain where as appeared precipitation reaction by DAS-ELISA and DTBIA ( "'Ghazal " et al ., " 2008 "').

Before Jaffe, Neubauer described a similar precipitation reaction by mixing creatinine with zinc chloride ( ZnCl 2 ) and performing a Weyl's test the addition of SNP to NaOH and then incubating with acetic acid ( CH 3 CO 2 H ) to develop a color change . was being used to remove protein from spectrophotometrically at 520 nm.
