Lets assume that the bottle containing the NaOCl has been marked with X % NaOCl.
a) Experimental % NaOCl is lower than value on bottle.
If NaOCl is decomposed into NaCl and NaClO2, then the amount of NaOCl decreases while the other compounds increases. So, in the % composition calculation, the numerator decreases resulting in % composition < X % mentioned on the bottle.
b) Experimental % NaOCl is higher than value on bottle.
Let Y be the titration volume (at endpoint) required for X % NaOCl, and Z be titration volume (past endpoint) in the experiment.
Since Z > Y, then experimental composition > X% mentioned on bottle
Add Answer to:
Would the following sources of error cause the ex than the value on the bottle? Briefly explain. a. NaOCl in the bleach has decomposed to NaCl and NaCIO, 1. perimental % NaOCl to be higher or low...
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
