Experiment #5: Acid Burn!!! Introduction The goal of this lab was to correctly prepare a 0.2M solution of NaOH‚ identify highly acidic household cleaning chemicals‚ and determine their concentration (molarity) through titrations using the previously prepared 0.2M NaOH solution. Experimental First‚ to create 0.5L of 0.2M solution of NaOH‚ standard 3M NaOH solution was obtained. Next‚ calculations were performed to determine the amount 3M NaOH necessary to create 0.5L of the 0.2M solution and‚ as

British mercantilism established itself with the help of the trans-Atlantic trade. Great Britain was then able to have adequate supremacy over the colonies to impose several acts such as the Navigation Acts and Molasses Act. Trade routes linked the American Colonies‚ West Indies‚ Africa and England. England‚ being the mother country‚ wanted a favorable balance of trade. The triangular trade is an example of mercantilism‚ or the idea that the mother country gains wealth and power by controlling

BEHAVIOUR OF AMINO ACIDS IN SOLUTION Abstract In this practical the acid-base behaviour of amino acids was assessed. Amino acids are amphoteric. They have the basic (amine) and the acidic (carboxylic) functional groups. These show the same type of equilibrium reactions that all weak acids and bases undergo‚ and the relative amount of each can be altered by adjusting the pH of the solution. For this practical glycine was used as a model to show this unique nature of amino acids. A series of

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

The Trans-Pacific Partnership Agreement (TPPA) is the biggest trade agreement in history‚ making up about 40 percent of the global economy with a projection of almost $30 trillion. Other than being the biggest trade agreement‚ TPPA is described as a secretive and multinational ‘free trade’ agreement lead by United States. The agreement is currently‚ be negotiated between 11 countries‚ which are Malaysia‚ New Zealand‚ Australia‚ Brunei‚ Chile‚ Peru‚ Singapore‚ Vietnam‚ Japan‚ Mexico‚ and Canada. The

Acid-base titration Aim To study the titration curve of a strong base-strong acid‚ strong base-weak acid and weak acid-strong base titrations Introduction Acid-base titrations are based on the neutralization reaction between the analyte and an acidic or basic titrant. When an acid and a base are present in a stoichiometric amount e.g. 1 mole HCl added to 1 mole NaOH‚ this means that the equivalent point has been reached in an acid-base system. The end point of an acid-base titration can be
