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.

Conclusion

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.
