Analysis methods for mixture of hydrochloric acid and sulfuric acid
++++++
Hi, I'm Yani from Indonesia.
I have a problem how to analysis hydrochloric acid in mixture of hydrochloric acid and sulfuric acid.
Can I analyze it with titration method? In my experience, the result of titration using sodium hydroxide will have a higher hydrochloric acid concentration than the industrial standard (the main analysis is percentage of hydrochloric acid). The industrial standard for hydrochloric acid in Indonesia is 30 to 33 %. I think it caused by presence of sulfuric acid on solution (there's barium sulphate precipitation when reacted with barium chloride).
Could u tell me about the right analysis methods for my problem?
Thanks a lot,

you check presence of HCl or chloride by adding 1% AgNO3; you can estimate the amount of HCl from chloride or amount of sulfuric from sulfate by gravimetry.
