When performing the hydrolysis of trimyristin with 1mL of 6M NaOH and 2mL water, why does this result in a slight purple solution?

Expert Solution

basic hydrolysis (saponification) on trimyristin affords sodium myristic acid and glycerol. Now again the myristic acid reacts with base to give sodium myristate (sodium salt of ester). Trimyristin is a white to yellowish-gray solid, when converts to it carboxylate salt it undergoes hydrolysis to give basic solution, hence solution becomes more alkaline. Remeber weak acid conjugate base always basic. Phenolphthalein blocks the blue light spectrum when exposed to alkaline substances, producing a pink to purple hue.

2. The hydrolysis of ATP is the cell’s most commonly used exergonic reaction when performing energy coupling. Explain energy coupling, why it is necessary, and how the hydrolysis of ATP fits into the process. Use vocabulary words such as “endergonic,” “exergonic,” “spontaneous,” and “nonspontaneous.” (8 points) Prokaryotic organisms do not have membrane-bound organelles. However, they are able to make ATP and survive. Assuming that bacteria cannot use their membranes to make ATP, which process can they still use in order...

When phospholipids are placed in water, why does a bilayer form? A. Phospholipids are naturally attracted to each other, forcing phosphate heads to face the aqueous areas. B. Lipids are hydrophilic and will from hydrogen bonds with the water, forcing the hydrophobic heads towards the middle of the bilayer. C. The polar tails will be attracted to the water and the nonpolar heads will be attracted to each other. D. The fatty acid tails are forced together away from the...

How does this process of standardization of NaOH works and why is KHP used (what does "KHP" stand for and what does the molecule look like?). Why was it necessary to standardize NaOH? Also, we used Phenolphthalein as an indicator. Find out what it looks like [show in the structure(s)] and what is the acid/base mechanism that leads to the pink color you observed.
