Chemistry: The Central Science, Chapter 17, Section 3. In Section 4.6 we briefly described titrations.
In an acid-base titration, a solution containing a known concentration of base is slowly added to an acid (or the acid is added to the base). Acid-Base Titrations and Buffered Solutions. (a) the initial point - This is essentially a weak acid (HA) (aqueous solution) scenario in which one can solve for [H+] via: or if an approximation can be made: (b) buffer region - In this region, the amount of strong base added is still not enough to neutralize completely the weak acid.
Prior to reaching the equivalence point, part of HA is neutralized to A-. Thus, the solution will now contain both HA and a significant amount of A-. Acid-Base Titrations and Buffered Solutions.
This is where body fat ends up when you lose weight. Despite society’s obsession with weight loss, a new study reveals that, surprisingly, most health professionals don’t actually know what happens to fat when we “lose it”.
The research conducted by a team at UNSW Science in Sydney calculated exactly what happens to our fat when we shed kilos, and revealed that doctor's leading theories are wrong - we don’t convert our missing mass into heat or energy, we breathe it out. Their results, published in the British Medical Journal, reveal that 10 kg of fat turns into 8.4 kg of carbon dioxide, which is exhaled when we breathe, and 1.6 kg of water, which we then excrete through our urine, tears, sweat and other bodily fluids.
“The correct answer is that most of the mass is breathed out as carbon dioxide. It goes into thin air,” said lead author of the paper Ruben Meerman, a physicist and TV presenter, in a press release. Laminar flow demonstrated. Evolution of... 15 Craziest Natural Phenomena on Earth.

Plastic Bottle Codes & Safety for Reuse - as Dr. Manny Alvarez Discussed on Fox News. #1 PETE is the most widely used plastic in water and soda bottles.
When exposed to heat or sunlight, the container will start to degrade. This will not be visible, but the harmful chemicals are breaking down into the contents of the bottle. This bottle should not be reused. How A Granade Works. Self Made Scholar - Free Self Education Classes Online. Where to Get the Best Free Education Online. PHIL PLAIT: Welcome to science. Phil Plait, better known as The Bad Astronomer, is an astronomer (obviously), noted skeptic and popular science writer.
His Bad Astronomy blog is one of the most popular science websites around and it’s where I get my regular science fix. This quote is taken from a speech Plait gave at a student science fair. He had no idea what he was going to say until he saw a news story on television the night before the fair. The story was a typical psuedo-science fluff piece that’s unfortunately seen too often on mainstream news.
It made Phil so angry he quickly wrote this speech in response. Words of Wisdom found in Math Formulas. Part of Nature cartoon by Stuart McMillen. Hints for Remembering Better.

Common indoor plants may provide a valuable weapon in the fight against rising levels of indoor air pollution.
NASA scientists are finding them to be surprisingly useful in absorbing potentially harmful gases and cleaning the air inside homes, indoor public spaces and office buildings. The indoor pollutants that affect health are formaldehyde, Volatile Organic Compounds (benzene and trichloroethylene or TCE), airborne biological pollutants, carbon monoxide and nitrogen oxides, pesticides and disinfectants (phenols), and radon. These pollutants contribute to ‘sick building syndrome’, which causes symptoms ranging from allergies, headaches and fatigue through to nervous-system disorders, cancer and death. Through studies conducted by NASA, scientists have identified 50 houseplants that remove many of the pollutants and gases mentioned above.
Dr. More information on this study as well as references and details on specific chemicals can be found on Dr. Dr. Buffers. Buffer Solutions A buffer solution is one in which the pH of the solution is "resistant" to small additions of either a strong acid or strong base. Buffers usually consist of a weak acid and its conjugate base, in relatively equal and "large" quantities.
