BUFFERS By: Luis P. Bazan‚ RPh.‚ Ph.D. A buffer solution is a solution of: 1. A weak acid or a weak base and 2. The salt of the weak acid or weak base Both must be present! A buffer solution has the ability to resist changes in pH upon the addition of small amounts of either acid or base. Consider an equal molar mixture of CH3COOH and CH3COONa CH3COOH (aq) H+ (aq) + CH3COO- (aq) Adding more acid creates a shift left IF enough acetate ions are present 16.3 Which of the following

Recrystallization of Benzoic Acid Objective To purify benzoic acid by recrystallization and gain experience with a basic organic laboratory techniques. Background Products of chemical reactions are often contaminated with impurities. One method for purifying chemicals‚ recrystallization‚ takes advantage of the differences in the solubilities of the desired products and the impurities and the tendency for the slow formation of crystals to exclude impurities from the crystalline solid.

melting point range of 152°C-154°C was recorded. After standardizing the melting device‚ a small sample of unknown carboxylic acid was placed in a capillary tube‚ and an arbitrary plateau of 200°C was set. When the sample started to melt at 150°C‚ another capillary tube containing a small amount of unknown sample was placed in the melting device‚ and the plateau was set to 135°C‚ 15°C below the expected melting point. After its temperature reached the plateau‚ the temperature increment was set at 1°C

adopting new technologies and are using feed acidifiers for supplementing the diets of animals. The market value of propionic acid as a feed acidifier was the highest in 2012‚ and is projected to grow with the increasing demand for feed acidifiers in the livestock industry. The benefits of feed acidifiers are leading the market demand in the feed industry. The fumaric acid market is comparatively small and is projected to grow at a CAGR of 5.8% from 2013 to 2018. The feed acidifiers market is projected

Titration Lab How Much Citric Acid is in Your Soda? PURPOSE To determine the molarity (concentration) of citric acid (H3C6H5O7) in various different citrus flavored sodas. BACKGROUND PRINCIPLES Popular sodas all strive for a somewhat sour (’tart’) flavor and manufacturers utilize acids to impart this taste. While there are a vast variety of different brands of sodas on the market‚ they can be broken into two main categories: dark or clear. This differentiation is not only a simple color

FRUIT ACIDS BY TITRATION AND CALCULATION OF THE SUGAR/ACID RATIO It is the sugar/acid ratio which contributes towards giving many fruits their characteristic flavour and so is an indicator of commercial and organoleptic ripeness. At the beginning of the ripening process the sugar/acid ratio is low‚ because of low sugar content and high fruit acid content‚ this makes the fruit taste sour. During the ripening process the fruit acids are degraded‚ the sugar content increases and the sugar/acid

What is acid rain? Rainfall made sufficiently acidic by atmospheric pollution that it causes environmental harm‚ typically to forests and lakes. What chemicals make rain acidic‚ and how does it happen? Besides water‚ and carbonic acid (from carbon dioxide dissolved in the rain droplets)‚ the primary components of acid rain are sulfuric acid‚ which comes from sulfur dioxide derived from the burning of coal‚ and nitric acid‚ which from nitrogen emissions. Where do these chemical come from?
