Can't Judge a Powder B

[Cheesy Pie]

Ex.: If it fizzes in HCl, say "Substance fizzes in HCl," not "Substance is basic."

Hmm ok, thanks. But if the color of the liquid is clear and it changes to orange, you'd write liquid is orange right? But what if it stays clear? Can you write no color change since you technically are observing that...?

[Cheesy Pie]

Say "liquid turned from clear to orange" or "liquid stayed clear."

Ok thanks

Just trying to actually be helpful on SciOly for once.

Say, if you add water to the powder, it turns into a "slushy" sort of mixture, what state of matter would it be? (would you write liquid, solid, colloid? etc.)

I would say that its a liquid, or you could say part solid and part liquid.
But the "slushy" comes from the powder absorbing the liquid.

Okay, thanks, ptkid! Also, just a quick question: how do you guys normally make observations? Are you allowed to make captions such as "Powder+H2O" and then under it have observations such as "clear"? Or do you have to say "Powder and water solution was clear?"
Also, say you included an "irrevelant observation" as one of your observations in the answer. Would you have points taken off?
haha that turned out to be a long question. Thanks in advance!

If you obsetve that powder+water is clear, write "water clear when powder added" or something along the lines of that.

For the irrelevant observation part, I would say it wouldn't be wrong fully but you may or may not get docked points. It really depends on the proctor and how they are feeling; so personally I'd try and put what is right and no more.
