This results in cleavage of phosphodiester bonds. 3. The product formed is 2’-3’ cyclic monophosphate derivative and it is further hydrolysed to 2’ and 3’ monophosphate nucleotides. The DNA lacks 2’-OH and therefore is stable ,under, this ,condition,. 7. The nucleophilic attack of base on 2’- …

Since the equation is in ,acidic, solution, you can use HCl or HNO 3. I'll use HCl. The most common dichromate that is soluble is potassium dichromate, so we will use that. Using those, we find this: 5HCl + K 2 Cr 2 O 7 + 3SO 2---> 2CrCl 3 + 3KHSO 4 + H 2 O. However, there is a problem. One too many K and Cl on the right-hand side.

Also, methyl and primary alcohols react ,under, strong HX acid conditions via SN2, while secondary, and tertiary alcohols react ,under, strong HX acid conditions via SN1 (HX = HCl, HBr, HI). All alcohols react via E1 reactions with H2SO4/ . Rearrangements are always a possibility in carbocation chemistry.

pH Effect on Heavy Metal Release from a Polluted Sediment
pH Effect on Heavy Metal Release from a Polluted Sediment

Under acidic conditions, Cd, Ni, or Cu are more likely to be released into the overlaying water. Modeling of metal leaching from sediments by Visual MINTEQ indicated that the metal leaching behavior by modeling fits well with the experimental values, so Visual MINTEQ is a useful model to determine metal species in solution over a large pH range.

Electrolysis of water - Wikipedia
Electrolysis of water - Wikipedia

Electrolysis of water, is the process of using electricity to decompose water into oxygen and hydrogen gas. Hydrogen gas released in this way can be used as hydrogen fuel, or remixed with the oxygen to create oxyhydrogen gas, which is used in welding and other applications.. Sometimes called water splitting, electrolysis requires a minimum potential difference of 1.23 volts
