Silver nitrate AgNC

The reaction with silver nitrate serves to determine the presence of chlorides both gravimetrically volumetrically in the former case, chlorine is weighed as AgCl in the latter, the vol of std AgNC>3 soln reqd for complete pptn of the chloride present in a known vol of soln is detd (Refs 2 4) (See also Refs 2a, 6 7)... 

Note that the information in Table 4.1 allows us to predict that AgCl is the white solid formed when solutions of AgNC>3 and KC1 are mixed Rules 1 and 2 indicate that KNO3 is soluble and Rule 3 states that AgCl is (virtually) insoluble. Figure 4.15 shows the results of mixing silver nitrate and potassium chloride solutions. 

An experiment showed that electrolysing silver nitrate solution, AgNC faq). using a current of 0.100 amperes for 30 minutes resulted in the cathode gaining a mass of 0.201 g. 

The structure of 2AgN03-succinonitrile revealed the presence of complex cations, [AgNC(CH2)2CNAg]2+, and ionic nitrate ions.161 The Ag—N distances were 197 pm and the C—N bond distance was close to that expected for a triple bond (112 pm). In AgC104-2(adiponitrile) the structure was in the form of a two-dimensional polymer with the adiponitrile acting as a bridge between silver ions. The silver ion was tetrahedrally coordinated by four N atoms with Ag—N distances of —228 pm.163...
