In this assignment I will describe making aspirin by using Method 2.

Decisions on how to work safely with hazardous substance are based on risk assessment. It is illegal to carry out a work activity involving hazardous substance without first writing a risk assessment. For this experiment I must use all equipment that is supplied by the teachers with the set of instructions. To keep away from any chemical hazardous I must wear lab coat, eye protection and gloves to keep myself away from any danger
It is important that careful consideration is given to any implication for health and safety. When starting any lab work in any laboratory labs health and safety legislations must be followed.
Equipment that will be needed for this experiment:
• Filter paper
• Ring stand with funnel...
