Mercury

Mercury in the water
• The existing forms of mercury compounds and their
transport and transformation in the environment are
directly related to solubility in water.
1) Hg solubility at 25 o C: 60 mg/L in pure water,25 mg/L in
deoxidized water;
2) Water-soluble salts:HgCl 2 , HgSO 4 , Hg(NO 3 ) 2 , Hg(ClO 3 ) 2 ;
3) Organic mercury:
water insoluble: diethyl mercury( 乙 基 汞 ) (CH 3 CH 2 ) 2 Hg
and ethylmercuric chloride( 氯 化 乙 基 汞 )CH 3 CH 2 HgCl;
slightly soluble:mercury phenylacetate( 乙 酸 苯 基
汞 )PhHgAc;
mercury acetate( 乙 酸 汞 )HgAc 2 has the highest solubility.
