How to determine if mystery liquid is dilute H2SO4, H2SO3 or both?
Question 1: He didn't have any NaNO3, so he substituted KNO3.
Am I right that this should still work? i.e. both oxidizers will oxidize sulfur to SO2 when burned?
Now the big question. How can I determine (chemically, electrically, numerologically -anything but orally or sexually :) ) whether this 150ml solution is dilute H2SO4, H2SO3, or a mix of both?
I know both chemicals have distinguishing physical properties (H2SO3 = on-your-*** sulfurous odor), but this is so diluted, none are apparent. All I have to go on is, it's 150ml of clear liquid with no odor and pH <1.
Thanks in advance.. Again.
