Chlorophyll molecule contains a "head" of porphyrin ring and a "tail" of chlorophyllin. Magnesium atom is located in the center of porphyrin ring and tends to be positively charged, while the nitrogen atom associated with it tends to be negatively charged, so porphyrin is polar and hydrophilic and can combine with protein.

The magnesium atom in porphyrin ring can be replaced by H+, Cu2 ++ and Zn2+. When leaves are treated with acid, H+ easily enters chloroplasts and often replaces magnesium atoms to form pheophytin, which turns leaves brown.
