    Is that in salt analysis?

    If so, the HCl should be concentrated. Did you notice anything during the test?

    If you can tell us that, we'll proceed with the explanation. :)

    Ahh okay, I understand now.

    What do you know about the reaction?

    Like, what type or reaction is it?
    What happens when HCl is added? What reacts with HCl?
    What do you know about aluminium?

    If you can answer those questions, I'm sure you'll understand better why HCl is added. If you can't, don't worry and post back.

    PS: Can you use the box at the bottom to reply instead of using the comment button? Thank you :)
