I am not an expert this is just something I picked up and trialed...I was very dubious about H202 and have since told everyone - I would be too scared to try it over night...ipomoea turbinata was a 20 minute soak and it germinated 24 hours later without chipping...which I don't do anymore..

On trials I noticed that viable seed or seed that looked viable did sink, dead seed did float. I think it was because there was something wrong with the seed coat, when the H202 came in contact it 'fizzed up'

Seray 53, I have heard that a soak in H202 can get rid of germination inhibitors, seed that requires stratification I wash in soapy water as well; I tried this with an impatiens species, but the final soak was in sterile water treated with 200ppm and I would alternate conditions, fridge in the night and room temp on the day.

I have posted a picture of seed I have treated with a 10 mins soak in H202 then put on a paper towel sprayed with GA3 (200ppm) and 2 drops superthrive to 500 mil of water. Any dead seeds I removed and sprayed everything with H202 including the remaining seeds followed by a wash in water.

I think it is still dead however notice the difference, possible increase in the chance of germination of 10 year old ipomoea tricolor, I think of it as trying to bring a mummy back to life!!!
