Question

Reaction of hydrogen and triton oxide

Answer 1

Explanation:

Triton X-100 (C

14H

22O(C

2H

4O)n) is a nonionic surfactant that has a hydrophilic polyethylene oxide chain (on average it has 9.5 ethylene oxide units) and an aromatic hydrocarbon lipophilic or hydrophobic group. The hydrocarbon group is a 4-(1,1,3,3-tetramethylbutyl)-phenyl group. Triton X-100 is closely related to IGEPAL CA-630 or former Nonidet P-40, which might differ from it mainly in having slightly shorter ethylene oxide chains. Thus Triton X-100 is slightly more hydrophilic than Igepal CA-630; these two detergents may not be considered to be functionally interchangeable for most applications

Answer 2

The effect of H2 evolution on the mass-transfer coefficient of cathode reduction of potassium ferricyanide at a mercury cathode was studied with the aim of (i) comparing the mass transfer behavior at a Hg cathode with that at solid electrodes under gas-evolving conditions and (ii) testing the effect of non-ionic surface-active agent on the mass transfer behavior of an H2-evolving Hg cathode. It is found that the mass transfer coefficient at the Hg cathode was much higher than the value at a solid cathode. The mass transfer coefficient at H2 evolving Hg was found to decrease in the presence of Triton-×-100 surfactant by an amount ranging from 62 to 82%, depending on the H2 discharge rate and the Triton-×-100 concentrations.
