In the preparation of the phenyldiazonium salt, sodium nitrite andhydrochloric acid were used instead ofdirectly adding nitrous acid. Why wasnitrous acid prepared in situ?Sodium nitrite and hydrochloric acid lowers thetemperature of the reaction.Sodium nitrite and hydrochloric acid are ortho-,para- directors.Nitrous acid may deactivate the phenyl ring.Nitrous acid is unstable and readily decomposes.

The substance to be analyzed – is deep-pink colored, highly soluble in water salt. Reaction with NH; gives blue-colored precipitate, which can be dissolved in NH3 surplus accompanied by dirty-yellow colored solution formation. After precipitation of cation by "sodium carbonate drawing out" method, supernatant was independently treated by silver nitrate solution and barium chloride solution (in acid medium in both cases) – any precipitation hasn't been observed. Addition of antipyrin in acid medium changes color to red. What kind of substance is this? Co(NO3)2 CuCl2 Co(CH;COO), FeSO4

4. Solid nickel carbonate (NiCO3) is pretty insoluble in water, as are many metal carbonates. But it is much more soluble in aqueous solutions of NaCN because nickel (II) reacts with cyanide anion to form a tetracyanonickelate complex. Nickel (II) is also mildly acidic, but you can ignore that part of the system if you want. A.) Write the balanced chemical equations AND the corresponding equilibrium constant expressions that explain the solubility behavior of nickel carbonate in aqueous 0.1 M NaCN. B.) Write the charge balance expression that applies to the BCE's you wrote above. C.) Write one mass balance expression for the system.
7. Draw out the chemical equations of the carbonic acid / bicarbonateequilibrium system, explain how the system responds to increase acidity.
Which are TRUE for the use of indicators with dichromate? Dichromate is orange and changes color to green when reduced. The color change is abrupt enough to serve as an indicator. The equivalence point for dichromate can be determined using Pt and calomel electrodes. Dichromate end points are determined using the distinct color changes of diphenylamine sulfonic acid or diphenylbenzidine sulfonic acid indicators. In basic solution, the orange dichromate solution changes color to yellow when reduced to chromate anion. The color change is abrupt enough to serve as an indicator.
