The experiment is trying to determine how much of a solution containing vitamin C is required to be added to 1 cm3 of blue chemical to change its colour from blue to clear. The experiment users an new and old lemon‚ orange and blackcurrant juice‚ each with varying amounts of vitamin C content. Each experiment has independent and dependent variables. The solutions of soft drinks contain different levels of vitamin C (with old and new varieties) will be the independent variables in the experiment

strategy‚ which was a result due to a changing US pharmaceutical market and a rapidly expanding India market. The two companies in this IJV were both significant players within their home countries‚ Eli Lilly and Company in the US and Ranbaxy Laboratories Limited from India. When the possibility of establishing a joint venture was approached in 1992‚ the Indian market for pharmaceuticals was becoming more open to foreign direct investment. Also India at the time was putting a limit on the amount

AMR was allowed to reach steady state conditions. Traditionally‚ steady state conditions are defined as the state when temperature at each thermocouple locations approximately does not change with time. However‚ and due to the limitation of the laboratory‚ and after several experiments found the initial control of the fluid flow rate was a difficult process‚ also the measuring of the actual time variation of the fluid flow rate. Furthermore‚ due to the little mass of fluid flow‚ the experiments didn’t

Daniel H. Perry Procedures of Measurement and Density of Sugar in Soda Introduction The main focus of this lab was to acquire a basic understanding of how to properly use measuring devices in order to determine properties of a liquid. These properties are volume‚ mass‚ and density. The following measurements were obtained in the lab: density of water‚ both density and concentration of aqueous sugar solutions‚ and density of various soft drinks with respect to sugar. Additional experience was
