Serotonin acts as a weak base and has a pkb = 3. 84. The ph of a solution made by adding 0. 025 m of serotonin in water is 2.4.
A molecule called serotonin delivers information between nerve cells in the brain and other parts of the body. Body processes like mood, sleep, digestion, nausea, wound healing, bone health, blood clotting, and sexual desire are all significantly influenced by serotonin.
Tryptophan, an important amino acid, is used to make serotonin. This amino acid, which must be ingested by food, is frequently present in foods including nuts, cheese, and red meat. Lower amounts of serotonin can result from tryptophan insufficiency. Anxiety or depression may come from this, among other mood disorders. The chemical serotonin is essential for elevating mood and lowering anxiety.

Answer:
When the solution (with phenolphthalein) changes to colorless
Explanation:
When titrating with HCl is common to add phenolphthalein as an acid-base indicator.
Phenolphthalein is pink or fucsia when added into a basic solution. On the other hand when it is in acid solutions, is colorless.
So, when titrating, the NaOH solution will be initialy pink due to the phenolphthalein and when reaching the equivalence point, that color will fade out into colorless. This is how you know you hace reached the equivalent point.
Elements in the same group tend to have very similar properties (D). This is due to the number of valence electrons each group has.
