Determine the volume of ncs- is needed for the titration
A 25.00 ml portion of 0.100 Ag+ is added to a solution which is having the 0.0010 mole of Cl-. This solution is then titrated with the 0.0500MNCS- to the end point. Determine the volume of NCS- is needed for the titration.

A chemist observed that it would not readily dissolve in HCl, Solid black CuS is exceedingly insoluble, but would react with concentrated HNO3 resulting in a solution containing Cu2+, among other things.
A mixture which is having 0.3 g of CuCl and Cu (IO3)2 is made. The mixture is 46% Cu(IO3)2 and 54% CuI. At 20 deg C if the solubility of CuI is 0.0072g per 100.0g of water and the solubility of Cu(IO3)2 is 0.4 g per 100.0g of water at the 20deg C.
A sample which is having 0.1219 g of solid magnesium is burned in a constant-volume bomb calorimeter that has a heat capacity of 1769 J/°C when the calorimeter contains exactly the 241 g of water, and the temperature increases by the 1.126°
Determine the maximum concentration of NCS- ion can exist in solution before AgNCS begins to precipitate. Suppose you start to add thiocyanate ions to a solution in which themolarity of the silver ion are initially 0.1M.
