Titration of Copper chloride
When you titrate copper chloride (CuCL2) with Sodium Hydroxide to find the amount of free H+ ions not tied up with copper ions the procedure is a 2:1
ratio in the actual titration calculations because:
CuCl2 + 2NaOH => Cu(OH)2 + 2NaCl
Yet the copper chloride is rich in the HCl, where normally a titration with NaOH would require a 1:1 ratio in titration calculations.
I have in my notes from this site records of where the 1:1 ratio was used and I do not understand why, since you are seeking a neutralisation between
the copper chloride with sodium hydroxide to establish molarity of copper chloride that is free H+ ions in solution.
‘Calcination… is such a Separation of Bodies by Fire, as makes ‘em easily reducible into Powder; and for that reason ‘tis call’d by some
Chymical Pulverization.’ (John Friend, Chymical Lectures London, 1712)
Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. (William Penn 1644-1718)
The very nature of Random, Chance development precludes the existence of Order - strange that our organic and inorganic world is so well defined by
precision and law. (me)
