The answer was methanol, no doubt about it.

What was the acid and the base in that stupid hydrogen ion question? I got H2S for the acid and H2O for the base. For the next part I put water was acting as the acidic thing.

For the MC question just reverse the top one and add the other two I think.

Edit: I just read that you were talking about the second part.

I ended up with a really small volume. Something like 900 Coulombs for the charge. (0.5 x 60 x 30)

193,000 for 24 litres, so 900 C for around about 0.112 litres. Strange... unsure.gif
