41. Its conjugate base is the PW 12 O 40 3 " anion . 42. These annulynes reacted with potassium metal to form radical anions and dianions. 43. Cyclopentadienyl is formally related to cyclopentadienyl anion by one-electron oxidation. 44. Spontaneous rearrangement kicks off a carboxylate anion to produce the isocyanate intermediate. 45. Solutions contain tetrahedral [ HF 2 ] " anions . 46. Anion channels were identified as important controllers of stomatal closing.47. It dissolves slowly in hydrofluoric acid to give fluorohafnate anions . 48. In the hexahydrate, the nitrate anions are not bonded to nickel. 49. Similarly each anion is surrounded by a cloud with net positive charge. 50. This anion has been of great theoretical interest to the chemistry community.
