Textbook Question
Chapter 11, Problem 11.105QP
In 2009, thousands of babies in China became ill from drinking contaminated milk. To falsely boost the milk’s protein content, melamine (C3H6N6) was added to diluted milk because of its high nitrogen composition. Unfortunately, melamine forms a precipitate by hydrogen bonding with cyanuric acid (C3H3N3O3), another contaminant present. The resulting stonelike particles caused severe kidney damage in many babies. Draw the hydrogen-bonded complex formed from these two molecules.

The amount of tartaric acid is responsible for the tartness of wine and controls the acidity of the wine. Tartaric acid also plays a very significant role in the overall taste, feel and color of a wine. Tartaric acid is a diprotic organic acid The chemical formula for tartaric acid is C4H6O6 and its structural formula is HO2CCH(OH)CH(OH)CO2H.
A 50.00 mL sample of a white dinner wine required 21.48 mL of 0.03776 M NaOH to achieve a faint pink color. Express the acidity of the wine in terms of grams of tartaric acid, H2C4H4O6 (M. M. = 150.10) per 100 mL of wine. Assume that the two acidic hydrogens are titrated at the end point.
MM H2C4H4O6 = 150.10
MM NaOH = 40.00
Below is the balanced chemical equation for this titration.
Alkaloids are basic nitrogen-containing compounds of plant origin, many of which are physiologically active when administered to humans. Ingestion of coniine, isolated from water hemlock, can cause weakness, labored respiration, paralysis, and eventually death. Coniine is the toxic substance in the “poison hemlock” used in the death of Socrates. In small doses, nicotine is an addictive stimulant. In larger doses, it causes depression, nausea, and vomiting. In still larger doses, it is a deadly poison. Solutions of nicotine in water are used as insecticides. Cocaine is a central nervous system stimulant obtained from the leaves of the coca plant.Classify each amino group in these alkaloids according to type (primary, secondary, tertiary, aliphatic, aromatic, heterocyclic).
Cream of tartar is a white powder sometimes used in baking. (It's what separates a tangy, chewy snickerdoodle from an ordinary cinnamon-coated sugar cookie. The acid in the cream of tartar gives snickerdoodles their distinctive tangy flavor, and the chew happens because cream of tartar prevents sugar in the cookie dough from crystalizing into crunchiness. Allrecipies.com) Cream of tartar (KHC4H4O6) is the conjugate base salt of tartaric acid (shown to the right). The Ka for another similar acid is 8.7×10-3. What is the standard Gibb's free energy (in kJ/mol) for the dissociation of that other acid?

- Part A The chemical 5-amino-2,3-dihydro-1,4-phthalazinedione, better known as luminol, is used by forensic scientists in analyzing crime scenes for the presence of washed-away blood. Luminol is so sensitive that it can detect blood that has been diluted 10,000 times. A basic solution of luminol is often sprayed onto surfaces that are suspected of containing minute amounts of blood.

Salicylic acid occurs in small amounts in the leaves, bark, and roots of some vegetation (most notably historically in the bark of the willow tree). Extracts of these plants have been used as medications for centuries. The acid was first isolated in the laboratory in 1838.

What is the pH of a saturated solution of the acid (solubility = 1.8 g/L). (b) Aspirin was discovered as a result of efforts to produce a derivative of salicylic acid that would not be irritating to the stomach lining. Aspirin is acetylsalicylic acid, CH3CO2C6H4CO2H.
