Synopsis The objective of this experiment is to enable us to conduct the synthesis of aspirin, reinforce the skills of recrystallisation and reinforce the technique of melting point determination. It is carried out to form ester from an acid and an alcohol. The main procedures are preparation of aspirin, recrystallisation of aspirin and lastly determining…

Introduction It may be defined as: “A neurosurgical procedure wherein the connections to and from the brain’s prefrontal cortex are cut.

Introduction The redox reaction in an electrolytic cell is nonspontaneous. Electrical energy is required to induce the electrolysis reaction. An example of an electrolytic cell is shown below, in which molten NaCl is electrolyzed to form liquid sodium and chlorine gas.

Introduction: This experiment was planned to study how different temperatures can affect the loss of vitamin C in orange juice stored for a fixed period of time. Equal volume of freshly squeezed orange juices with known (initial) vitamin C concentration were stored at different temperatures i.e. 10°C, 20°C, 30°C, 40°C, 50°C and 60°C for a…
