So it is a catalyst.
A better catalyst.
Too true, but "Sea Squid" wanted "a magic catalyst" which helps "reduce
the cost" of breaking down water into H2 and O2 by 50%, which betrays a
teenage underlying lack of knowledge of economics, chemistry and
physics, so it seemed appropriate that he could conduct a safe
experiment in his mother's kitchen using some AA cells without spilling
on the floor or work surfaces, and his question was how to collect the
gas. I gave him the same answer I'd give to my own grandson.
Have a nice day, Rich. It's his mother that will be coming after YOU
when her wedding band is sawn in two and the place stinks from a
mix of H2SO4 and oven cleaner instead of some spilled salty water.
