Akin to its use for pickling, hydrochloric acid is used to dissolve many metals, metal oxides and metal carbonates. The conversions are often depicted in simplified equations: Zn + 2 HCl → ZnCl 2 + H 2 NiO + 2 HCl → NiCl 2 + H 2 O CaCO 3 + 2 HCl → CaCl 2 + CO 2 + H 2 O. These processes are used to produce metal chlorides for analysis or ...
Dorzolamide, sold under the brand name Trusopt among others, is a medication used to treat high pressure inside the eye, including in cases of glaucoma. [3] It is used as an eye drop. [3] Effects begin within three hours and last for at least eight hours. [3] It is also available as the combination dorzolamide/timolol. [3] [4]
For example, sulfuric acid (H 2 SO 4) is a diprotic acid. Since only 0.5 mol of H 2 SO 4 are needed to neutralize 1 mol of OH −, the equivalence factor is: f eq (H 2 SO 4) = 0.5. If the concentration of a sulfuric acid solution is c(H 2 SO 4) = 1 mol/L, then its normality is 2 N. It can also be called a "2 normal" solution.
X = number of atoms of carbon, Y = number of atoms of hydrogen, Z = number of atoms of oxygen, and M = number of atoms of metal (metallic oxide produced). In the case of TNT (C 6 H 2 (NO 2) 3 CH 3), Molecular weight = 227.1 X = 7 (number of carbon atoms) Y = 5 (number of hydrogen atoms) Z = 6 (number of oxygen atoms) Therefore,
3-MCPD (3-monochloropropane-1,2-diol or 3-chloropropane-1,2-diol) is an organic chemical compound with the formula HOCH 2 CH(OH)CH 2 Cl. It is a colorless liquid. The compound has attracted notoreity as the most common member of chemical food contaminants known as chloropropanols. [1] It is suspected to be carcinogenic in humans. [2]
For example H 3 O + CuCl 2 − forms in concentrated hydrochloric acid. [15] Chloride is displaced by CN − and S 2 O 3 2−. [12] Solutions of CuCl in HCl absorb carbon monoxide to form colourless complexes such as the chloride-bridged dimer [CuCl(CO)] 2. The same hydrochloric acid solutions also react with acetylene gas to form [CuCl(C 2 H 2)].
Pramocaine (INN and BAN, also known as pramoxine or pramoxine HCl) is a topical anesthetic discovered at Abbott Laboratories in 1953 [1] and used as an antipruritic.During research and development, pramocaine hydrochloride stood out among a series of alkoxy aryl alkamine ethers as an especially good topical local anesthetic agent. [1]
The compound is most easily prepared by treatment molybdenum trioxide with concentrated hydrochloric acid: [2] MoO 3 + 2 HCl → MoO 2 Cl 2 + H 2 O. MoO 2 Cl 2 can also be prepared from MoOCl 4: [3] MoOCl 4 + O(Si(CH 3) 3) 2 → MoO 2 Cl 2 + 2 ClSi(CH 3) 3. It is also prepared by chlorination of molybdenum dioxide: [4] MoO 2 + Cl 2 → MoO 2 Cl 2
