Sorry that's what I meant.
"So more ammonia means reduction in ammonia and more of ammonium."
Wait but how is this related to the question? lol sorry I am finding it so confusing to piece everything together.
"The ammonia is limiting because before the optimum, the volume of ammonia is decreasing, and the volume of Cu2+ ions increases. So the amount of ammonia decreases and the amount of copper ions increases. In this case the decrease in amount of ammonia is whats causing the any further increase in the formation of the blue preciptate [Cu(H2O)4(OH)2]. For example, if there was 2cm3 of Cu^2+ and 8cm3 of ammonia solution, then there will be X amount of the precipitate with absorbance of 0.34.
Now if I had the same 2cm3 of copper(II) ions but with more ammonia eg 10 cm^3 then there will be more preciptate formed ( > X) hence the absorbance would be greater than 0.34. Because the ammonia is limiting, we aren't getting the maximum mass of blue precipate for a given volume of Cu^2+ ions."
Sure, the bold makes sense -however just shown below, the volume of
copper increases,the volume of ammonia decreases. Why do you refer to the same volume of copper ions when the volume of copper ions is in fact increasing from tube to tube.
Can you please kindly let me know on this one as well?
