Web13 Points. Because electrolysis takes place with minimum no of alkanoicacid salts therefore methane cannot be prepared. methane could not be prepared by Kolbe electrolysis method as there is formation of alkyl radicle and two alkyl radicle combine to form alkane .but in methane there is only one carbon so it is not prepared.

WebAnswer (1 of 2): 100 mL at 0.01 M is 1.0 mmol NaOH. pH = 14 + log(0.01) = 12. 4 OH^- \rightarrow O_2 + 2 H2O + 4 e^- 2 H_2O + 2 e^- \rightarrow H_2 + 2 OH^- Summing up: 2 H_2O \rightarrow 2 H_2 +O_2 So, interestingly, this is just the electrolysis of water. And, more importantly for this ex... WebMar 8, 2024 · [HCOONa] = $\ce{0.012 / 0.08 = 0.15M}$ Using the Henderson–Hasselbalch equation: pH = pKa + log [HCOONa]/[HCOOH] = $\ce{3.75 + 0.60 = 4.35}$ So my answer is that the pH of the buffer is $\ce{4.35}$ Answer key. However, in our answer key, they found the new concentration of HCOOH and HCOONa by simply taking: [HCOOH] = $\ce{(0.05 …
For commercial use, sodium formate is produced by absorbing carbon monoxide under pressure in solid sodium hydroxide at 130 °C and 6-8 bar pressure: CO + NaOH → HCO2Na Because of the low-cost and large-scale availability of formic acid by carbonylation of methanol and hydrolysis of the resulting methyl formate, sodium formate is usually prepared by neutralizing for… WebDecarboxylation is a chemical reaction that removes a carboxyl group and releases carbon dioxide ( CO 2 ). Usually, decarboxylation refers to a reaction of carboxylic acids, removing a carbon atom from a carbon chain. The given reaction involves removal of carbon dioxide molecule, therefore, it is a decarboxylation reaction. Option B is correct.
Webelectrolysis, process by which electric current is passed through a substance to effect a chemical change. The chemical change is one in which the substance loses or gains an electron (oxidation or reduction). The process is carried out in an electrolytic cell, an apparatus consisting of positive and negative electrodes held apart and dipped into a …
