Sodium thiosulfate into sulfuric acid
Hi, I just had this idea (im not gonna do it because I dont have the right safety equipment) That putting Sodium thiosulfate into HCl would generate
sodium chloride, sulfur, sulfur dioxide, and water. My idea is to bubble the sulfur dioxide into water making sulfuric acid. would this work?
Thanks.

No
SO2+H2O<==>H2SO3 not H2SO4

As bismuthate said, no, you will not generate sulfuric acid. Instead you will generate sulfurous acid or an equivalent solution of sulfur dioxide in
water. There are plenty of threads on making sulfuric acid on the forum, enough to entertain you for hours upon hours. Essentially you need to
oxidize your sulfur dioxide further to sulfur trioxide or oxidize your solution further to sulfuric acid.

What about dissolving sulfur dioxide in hydrogen peroxide? That should oxidize the sulfur dioxide to sulfuric acid.
I wouldn't waste thiosulfate on sulfuric acid though, because burning sulfur is a faster way to produce sulfur dioxide.
At the end of the day, simulating atoms doesn't beat working with the real things...

Have it onhand to deal with iodine. The iodine clock reaction is fun and uses thiosulfate.

Iodometry in neutral/alkaline conditions.
Complexation of silver (dissolving AgCl, e.g.)

It's a method of determining iodine purity, similar to a acid base titration, because the iodine reacts with the sodium thiosulfate reduces the iodine
according to the following reaction 2Na2S2O3 + I2 --> Na2S4O6 + 2NaI
