Back titration of ammonium chloride
Not what you're looking for?
In a labratory. A solution of Ammonium chloride was given, for us to find the concentration by techniques of back titration. NaOH was added to the diluted ammonium chloride and heated. Then Titrated with HCL adding few drops of bromocresol green indicator. Colour turned yellow.
What does this mean? I have done the calculation. here are the results:
Volume of hcl used=23.50ml
Moles of NaOH=.001773
Moles of NH4CL=0.02216
Gram of NH4CL=237g/L
What does this all means.
