Silver metal is not easily oxidized, and does not react with oxygen-saturated water. However, when excess NaCN is added to a suspension of silver particles, some silver dissolves. If oxygen is removed (e.g., by bubbling nitrogen through the solution), the dissolution reaction stops. Write a balanced equation for the dissolution reaction (hint: it is a redox reaction).
Homework Answers
4Ag (s) + O2 (g) +4H+ (aq) + 8 CN- (aq) à 4 [Ag(CN)2]- + 2 H2O(l)
Oxidation state of silver Ag(s) is zero, when reacts with 8 moles of sodium cyanide (acidic medium) in the presence of oxygen produces , high spin silver complex.
The oxidation state of Silver in [Ag(CN)]- complex is +1. Hence, in the reaction the oxidation state of silver is changes from zero to +1. Silver gets oxidized.

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
