First of all, the thermometer flaw; we must record the initial time of the water to know what type of reaction is occurring and read thermometer in on eye level. It's very crucial if we groups keep making the flaws, the experiment will become unreliable. ...read more.


It proves that the energy from surrounding is absorbed to into the system which is the solutions and breaks the chemical bonds. The only exothermic is NaOH which final temperature rise by 11�C from its initial temperature. It proves that the energy from the system is unleashed to the surrounding marking a chemical bonding. ...read more.

    and at a higher value if the rate of reaction is higher. Since water's reaction with sodium is so violent, xanthan gum's pseudoplasticity at higher concentrations must be taken into account as the movement of the sodium in the water during the reaction may cause the viscosity to fall as the sodium displaces the solution kinetically.
