*Easier* for sure to buy the silver oxide, but, unless you count
collateral damage, how could it be *cheaper*?
At $147/lb, that's not quite $9 /ounce, or 30 cents a gram (did I figure
that right -- $9 divided by 29???). Then wouldn't the silver oxide amount
to a greater weight than the silver nitrate you started with, because
oxide is *added*? Or does oxidizing take away weight? (I had chemistry in
the 10th grade, & they hardly had the periodic table then. )
