What do you notice about the shade of blue in the solution over a period of about 5 minutes?
it loses the awesome blue tint and becomes clear-ish

rule 3
What is a base? (Station 6)
A substance, that when dissolved in pure water, increases the concentration of hydroxide ions.
How do you know that O₂ is being produced in Station 4?
Because there was no "pop" but the splint relighted when reinserted...
What evidence do you have to support that Station 2 released hydrogen gas?
There was a loud and startling "pop" that scared Vamsi...
