The pKa of KHP is 5.4, so its pH buffering range would be 4.4 to 6.4; however, due to the presence of the second acidic group that bears the potassium ion, the first pKa also contributes to the buffering range well below pH 4.0, which is why KHP is a good choice for use as a reference standard for pH 4.00.
The OSHA definition is arguably broad enough to include oxygen-deficient circumstances in the absence of "airborne contaminants", as well as many other chemical, thermal, or pneumatic hazards to life or health (e.g., pure helium, super-cooled or super-heated air, hyperbaric or hypo-baric or submerged chambers, etc.).
The monopotassium salt, potassium hydrogen phthalate is a standard acid in analytical chemistry. Typically phthalate esters are prepared from the widely available phthalic anhydride. Reduction of phthalic acid with sodium amalgam in the presence of water gives the 1,3-cyclohexadiene derivative. [13]
[24] [25] Dimethyl phthalate has been also used as an insect repellent and is especially useful against ixodid ticks responsible for Lyme disease. [26] and species of mosquitoes such as Anopheles stephensi, Culex pipiens and Aedes aegypti, [27] [28] [29] Diallyl phthalate is used to prepare vinyl ester resins with good electrical insulation ...
At the time, addicts were lucky to find a hospital bed to detox in. A hundred years ago, the federal government began the drug war with the Harrison Act, which effectively criminalized heroin and other narcotics. Doctors were soon barred from addiction maintenance, until then a common practice, and hounded as dope peddlers.

A hospital-acquired infection, also known as a nosocomial infection (from the Greek nosokomeion, meaning "hospital"), is an infection that is acquired in a hospital or other healthcare facility. [1] To emphasize both hospital and nonhospital settings, it is sometimes instead called a healthcare-associated infection . [ 2 ]
The Agency for Healthcare Research and Quality (AHRQ) is the Federal authority for patient safety and quality of care and has been a leader in pediatric quality and safety. AHRQ has developed Pediatric Quality Indicators (PedQIs) with the goal to highlight areas of quality concern and to target areas for further analysis. [ 121 ]
