Weak Base + Its Congregate Acid
A visible-light spectrophotometer can determine the concentration of a solution
- The normal melting point of a solid is defined as the temperature at which the solid and liquid are in equilibrium at a total pressure of 1 atmosphere.
When excess ammonia is added to a solution of Cu(NO3)2, the color of blue will be darker.
Cu(NO3)2 + 4NH3 = [Cu(NH3)4]](NO3)2
Adding Ammonia To Copper II Nitrate.
(left) Solution of blue Cu(NO3)2*6H2O (complex ion is Cu(H2O)6 +2).
(right) Addition of NH3(aq) forms deep blue complex ion [Cu(NH3)4(H2O)2]2+.
- The standard reduction potential is an intrinsic property. It will not change by the coefficient.
SO2 is a polar molecule, so it will deviate from ideal behavior.
