###### Question: 22. What will be the concentration of Ni in a solution that is made at 25°C and a high pH by adding 1.0 mL of 0.250 M Ni(NO3)2 to 100 mL of 0.058 M ammonia? You can assume that all of the Ni(NO3)2 originally dissolves to pro- duce Ni2+ and NO3 and that the value of [NH3] at equilib- rium is approximately equal to the analytical concentration of ammonia.
