EXPERIMENT 2 ACID DISSOCIATION CONSTANT OF AN INDICATOR DYE OBJECTIVES Using spectrophotometric method: determine the wavelengths at which the acid and base forms of the dye in aqueous medium exhibit maximum absorption; determine the molar absorptivities of the acid and base forms of the dye and estimate an unknown concentration of the dye in solution using the Beer-Lambert’s Law; and determine the acid dissociation constant of the indicator dye. THEORY The absorption or reflection of

With this set‚ scientists as of today had been able to organize the elements without much trouble and were able to discover unknown elements. Although there are many elements in the world and many of them have not always been known of‚ the periodic table had been created to classify these elements as well as the table’s corresponding patterns and trends

Acid rain is rain that has become acidic‚ because of air pollutants in the atmosphere. Rain has a normal pH level of around 5-5.5 which is only slightly acidic. 7 on the pH scale is the neutral and anything below that is considered acidic. Acid rain has a pH level around 4 which is 10 times more acidic. Acid rain can fall in many different ways and has many effects on the environment. Acid rain is caused by air pollutants in the atmosphere. These air pollutants are mainly from man made resources

Synthesis of benzilic acid from benzoin utilizing a multi-step reaction. Names: Arian Karim TA Name: Sayantan Das Lab Day & Time: Thursday 7:30-11:40 Lab Section #: Abstract The main purpose of this experiment was to synthesize benzilic acid from benzoin. This requires a multistep synthesis with benzyl as an intermediate product. The first step required HNO3 as an oxidizing agent and the second step required KOH and HCl. The percentage yields of benzil and benzilic acid were 59.5% and 21

Acid Rains There are three gases which could cause acid rain‚ which are Sulphur Dioxide (sulphuric acid)‚ NOx (oxides of nitrogen which produce nitric acid) and also perhaps Carbon Dioxide (weak carbonic acid)‚ produces these acids because these gases dissolve in rain water/ precipitation and this forms a weak version of the acid‚ as the gases dissolve it lowers the pH of the rainwater. I think that there has been a increase in the production of acid rain‚ due to the fact that the country as a

It required the immense research and determination of the scientist Dmitri Mendeleev to show us that all elements followed a natural form and provided us with the first decent periodic table. There are 111 elements recognised today by IUPAC and they are arranged in the periodic table in horizontal groups and vertical periods. The eight groups consist of the alkali metals‚ the alkaline
