Will you pick one of the right chemicals and make yourself some lovely table salt, or will your concoction explode and end in disaster?
Can You Pick The Right Chemical And Not Blow Up The Lab?
You chose sodium hydroxide, so when you added it to hydrochloric acid you got sodium chloride and water. Well done! You made your salt, and you didn't blow up the lab.
You chose copper(II) oxide, which reacted with the acid to make copper(II) chloride and water. It looks pretty, but it wasn't what you were supposed to make. Also it's toxic, so you should definitely not sprinkle it on your chips. Soz. Try again.
You chose sodium carbonate, so when you added it to the hydrochloric acid it made sodium chloride, carbon dioxide, and water. Congratulations!
You chose potassium, which you added to the hydrochloric acid and then quickly realised you'd made a mistake. Once the flames have died down, you'll get some potassium chloride, which is a salt, but it's not sodium chloride, so you better choose more wisely next time.
You chose iron(III) oxide and ended up making iron(III) chloride, which is definitely not table salt. It's not even the right colour. Try again.
You chose water which you added to your hydrochloric acid to make... just slightly diluted hydrochloric acid. I hope you added your acid to the water, though, rather than the other way round, otherwise you probably ended up with boiling acid on your hands. Nobody wants that. Better try again.
You chose zinc, which you added hydrochloric acid to and made, with a lot of fizzing, zinc chloride and hydrogen gas. The powder you got is crystalline and white so it looks a bit like salt, but it certainly doesn't taste like it.
You chose sodium, which was a pretty good bet. When you add it to your hydrochloric acid it fizzes explosively, but once all the hydrogen bubbles off you end up with sodium chloride. Congratulations!
You chose nitric acid. When you add it to the hydrochloric acid, it makes something called aqua regia that starts off colourless but then immediately turns orange and bubbles and fumes. This corrosive liquid is pretty impressive and can dissolve gold and platinum – but it's not what you were supposed to make. Zero points for you. Try again.
