Silver bromide (slightly yellowish white) and silver iodide (bright yellow) are also significantly more photosensitive than is AgCl. [1] [4]: 46 AgCl quickly darkens on exposure to light by disintegrating into elemental chlorine and metallic silver. This reaction is used in photography and film and is the following: [5]
Commercial reference electrodes consist of a glass or plastic tube electrode body. The electrode consists of a metallic silver wire (Ag (s)) coated with a thin layer of silver chloride (AgCl), either physically by dipping the wire in molten silver chloride, chemically by electroplating the wire in concentrated hydrochloric acid (HCl) [3] or electrochemically by oxidising the silver at an anode ...
In the binuclear ion [Co 2 (OH 2) 10] 4+ each bridging water molecule donates one pair of electrons to one cobalt ion and another pair to the other cobalt ion. The Co-O (bridging) bond lengths are 213 picometers, and the Co-O (terminal) bond lengths are 10 pm shorter. [10] The complexes [Mo 2 (H 2 O) 8] 4+ and [Rh 2 (H 2 O) 10] 4+ contain metal ...
Mn 3 O 4: −1387 Permanganate: Aqueous MnO − 4: −543 Mercury(II) oxide (red) Solid HgO −90.83 Mercury sulfide (red, cinnabar) Solid HgS −58.2 Nitrogen: Gas N 2: 0 Ammonia (ammonium hydroxide) Aqueous NH 3 (NH 4 OH) −80.8 Ammonia: Gas NH 3: −46.1 Ammonium nitrate: Solid NH 4 NO 3: −365.6 Ammonium chloride: Solid NH 4 Cl −314.55 ...
Orbitals of same symmetry and similar energy levels can then be mixed to form a new set of molecular orbitals with bonding, nonbonding, and antibonding characteristics. In the simple MO diagram of H 2 O , the 2s orbital of oxygen is mixed with the premixed hydrogen orbitals, forming a new bonding (2 a 1 ) and antibonding orbital (4 a 1 ).

The essence of Brønsted–Lowry theory is that an acid is only such in relation to a base, and vice versa. Water is amphoteric as it can act as an acid or as a base. In the image shown at the right one molecule of H 2 O acts as a base and gains H + to become H 3 O + while the other acts as an acid and loses H + to become OH −.
Around 2 to 4 inches of rain is expected along the coast from the Pacific Northwest into central California, while the Sierra Nevada could see up to a foot of snow. Winter weather alerts remained ...
