Part 8: Testing for ammonia/ammonium ion Note: NH3(g) H2O(l) NH4 (aq) OH- (aq) (weaker base) (stronger acid) 2) What did you observe when testing ammonia solution with litmus paper

Explanation:

Hello!

In this case, since ammonia is a weak base because in the presence of water it ionizes to ammonium ions and hydroxide ions, which provide the basic character, when a strip of universal litmus paper is put inside an ammonia solution, we can evidence it turns blue according to the scale provided on the attached picture.

Whereas it is noticed that a blue coloration corresponds to an average pH of about 11-12 which matches with the reported value (11.6).

Best regards!

diaria maybe go see a doctor about that

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
