if 100 ml of the acid is neutralised by 100 ml of 0.4M NAOH,the purity of concentrated HCL is?specific gravity=1.6

5 Answers

i am getting 0.9125 percent purity of HCl

answer is 12%

millimoles of naoh=400=0.4moles
moles of the acid =0.4
weight of hcl=0.4*36.5=14.6
from given weight of hcl=100*1.2=120
so %of hcl=14.6/120*100=12%

sanjana,
so many blunders!!!!!!!!!

hello

millimoles of acid=0.04 not 0.4 recheck ur calculations else u have posted incorrect values in question.

u wrote specific gravity=1.6 and urself took it as 1.2,whoo,what a blunder.

post the correct question.!!!!

oops
