How does adding NH3 into the cell with CuSO4 affect the voltage measurement? The other cell also has CuSO4 but a different M.
Homework Answers
The addition of NH3 to a solution of Copper sulphate i.e. Copper(II) ions causes the formation of copper ammonia complex, (Cu(NH3)4)2+. This reduces the concentration of Cu2+ ions in the solution. Thus, it reduces the voltage of the half cell and of course the voltage of a cell.

Adding all numbers together, Apple shares rose 840% in the Eight years from the introduction of the Iphone on January 1st, 2007. However Now, cash has become a negative value for fund managers that have the intent to invest in Apples Shares. Apple's cash hoard could not achieve 2 % return threshold. Apple's low retum assets started to increase. It has a prediction for the...

Answer the following question about NH3 A) Difference in state—How does the compound’s use change in a different physical state or when mixed with other compounds at different concentrations? B) Difference in the reactivity of the compound with the reactivity of a similar compound—Does more or less reactivity change the way in which it is used? C) Change in the heat of reaction—Discuss the effects of changing the reaction temperature; for example, would the change make it unsafe, too slow,...

How does adding water to antimony trichloride affect (shift) the equilibrium even though it doesn't show up on the equalibrium constant expression? Is it because it dilutes the concentrations of the Cl- ions? Which way does it shift? SbCl3 (aq) + H20(l) <---> SbOCl(s) + 2H+(aq) + Cl-(aq)
