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]
4 (aq) → Ag 2 CrO 4 (s) (K sp = 1.1 × 10 −12) The solution needs to be near neutral, because silver hydroxide forms at high pH, while the chromate forms Ag 2 Cr 2 O 7 or AgHCrO4 at low pH, reducing the concentration of chromate ions, and delaying the formation of the precipitate. Carbonates and phosphates precipitate with silver, and need ...
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 near-infrared range liquid water has absorption bands around 1950 nm (5128 cm −1), 1450 nm (6896 cm −1), 1200 nm (8333 cm −1) and 970 nm, (10300 cm −1). [ 19 ] [ 20 ] [ 15 ] The regions between these bands can be used in near-infrared spectroscopy to measure the spectra of aqueous solutions, with the advantage that glass is ...

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 ...

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.
