Unit 4B Task 2 Title Recrystallization of benzoic Acid Aim Equipment 1. Erlenmeyer flask 2. Graduated cylinder 3. Hot plate 4. Small beaker 5. Ice bath (if necessary) 6. Filter paper 7. Buchner funnel 8. Spatula 9. Weighing machine Method 1. Weighing paper was used to weigh approximately 1.00g of ‘impure Benzoic acid to produce re crystallization’. 2. Moved it to a 125ml Erlenmeyer flask. 3. Poured approximately 20ml of distilled water by using a graduated cylinder

Amino acid present in the lumen of the small intestine The goal is to cross through the epithelial cell membrane to enter into the epithelial cell’s cytoplasm – its charged cuz of side chains To get through the membrane the amino acid must cross the Simple columnar epithelial cells lining the apical surface of the small intestinal tract. These cells are impermeable to any harmful bacteria that may be ingested by the body‚ but permeable to necessary ions. Absorption of amino acids occurs through

Experiment 2 Acid/Base Titration John J. Purdue CHM 321 – Fall 2012 TA: Scott Cole Section 1 September 4‚ 2012 Unknown Concentration: X.XX ± X.XX M (@95% confidence interval) (adapted from a report prepared by N. Skrynnikov‚ 2009) Abstract The concentration of an unknown acid (HA) solution was determined by titration with a standardized solution of sodium hydroxide. The standardization of NaOH was done by titration with a solid acid sample‚ potassium hydrogen phthalate (KHP)‚ and phenolphthalein

Protein and Amino Acid Supplementation in Sports The popularity of increasing the “performance-enhancing” supplements‚ Protein and amino acids‚ has flourished among all athletes. This increase is attributed to the belief by many of the athletes that it provides endurance‚ strength and speed enhancement. Amino Acids (AA) enhanced physical feats‚ improved energy and recovery sooner from fatigue. The three vital Amino Acids which were given a high focal point among athletes are leucine‚ isoleucine

ANTACID WILL NEUTRALIZE STOMACH ACID THE BEST AND IS MOST COST- EFFECTIVE? Description This experiment was conducted to find out how effective different types and brands of antacids are at neutralizing acid. I also looked at the cost of each product in order to determine if my hypothesis would be correct. The experiment was done using 4 brands of antacid‚ Pepto-Bismol‚ Gaviscon‚ Tums and Tagamet. Hypothesis All the antacids will neutralize different amounts of acid but the most expensive one

Task 4 – The Maintenance of the Acid – Base balance in the body (D1) pH is measured based on its acidity and alkalinity. There are many substances around the body that have different pH values. A pH of 7 is usually considered neutral‚ neither acid nor alkaline‚ this is the pH of water. In the body the acids and bases need to be in very close balance‚ this is called ‘acid base homeostasis. If it goes off too far in either direction then it could be fatal to the body. For example in the body the blood

INTRODUCTION Sulphuric Acid is an important chemical‚ which has large-scale industrial uses. Its major user is the phosphate fertilizer industry. Other important applications are in petroleum refining‚ steel pickling‚ rayon & staple fiber‚alum‚ explosives‚ detergents‚ plastics and fibers etc. Sulphuric Acid Industry is very old and has been continuously adopting the technological developments. It started with Lead Chamber process followed by contact rocess with Single Conversion Single Absorption

I will also mention the time which was taken in the experiment‚ to see how fast the hydrochloric acid took with indigestion tablet with different concentrations. Indigestion tablets are alkali and they are used for to neutralise the excess acid in the stomach. Indigestion Tablet Indigestion is caused by excess acid in the stomach. The tablets neutralise some of this Acid and this is known as ‘Neutralization’ since it neutralizes the acid. In this
