Answer;
They indicate the acidity level. That is, the less pH, the more acidic
Hope it helps :)
11.82 x 1 mole / (molar mass)
The molar mass = 197 g/mol
11.82 / 197 = .06

The dots around the respective atoms represent the number of valence electrons each of the corresponding atoms have. Since nitrogen is more electronegative it is placed within the middle, it can also form the 3 covalent bonds, unlike chlorine which can only form 1 and thus is in the middle of the diagram. This structure has gained stability in that all of the atoms have 8 electrons in its outermost shell, if you were to count the shared electrons for each atom.
It helps shape and create the study of electromagnetism
