Introduction Rate of reaction is a measurement of the speed of reaction. There are many factors that could affect the rate of reaction. e.g. Concentration of the solution, temperature, surface area, catalyst, air pressure and stirring, etc. I decided to choose temperature as my changing variables to investigate the rate of reaction. Bisodel Tablet Bisodel tablet is mainly made up of calcium carbonate, which is alkali. It is used when people having stomachache or …showed first 75 words of 1932 total…

Also, the machine can also detect whether the tablet is totally dissolved and stop automatically. It can also reduce the man-made error. 4)Increasing the number of experiments could allow much more figures to calculate the averages.
