Factors affecting the refractive index of liquid Aim To find out the factors affecting the refractive index of liquid by using different temperature and concentration of salt solutions, glucose solutions, sucrose solutions and corn oil. Research and rationale Before doing this investigation, I have a few choices of topics, including properties of condom, centripetal force of a four wheel drive toy car, and refractive index. I started researching through the Internet. I have come across a web site called 'Brother Gregory investigate', 1 concerning measurement of refractive index. I found this experiment very interesting, using simple and easily available instruments and appropriate for A-level standard. I found that refractometry is very useful in measuring sweetness in food industry.2 The experiment in the web site is using glass, in order to make more variations, I choose to use salt and sugar solutions. Moreover, the refractive index of some liquids is already known, so that I...
