Acid-Base Reaction Temperature Conundrum

In summary, the speaker has been frustrated by discrepancies in their temperature measurements while conducting an experiment with NaOH and HCl. Despite following instructions and using the same equipment and solutions as other groups, their recorded temperature changes were significantly lower. They are seeking insight and possible solutions for future experiments.

Well this is something that has been aggravating me since I did the experiment at school and really just want to solve and not have it happen again.

My problem is while mixing varying mL of NaOH and HCl we (my group and me) were supposed to record the varying changes in temperature for the different mixtures, but for some odd reason the highest temperature change we recorded was 1.5°C and 0°C.
While other groups were able to do the same mixtures, but come up with temperatures that varied from 2.5°C to 7°C.

To possibly answer future questions we used the measurements the instructions pointed so that the solution always added to 50mL, used a styrofoam cup like everyone else to insulate the heat, and even cleaned the equipment after each mix.

Any insight into this is very helpful and well appreciated. Also Thanks in Advance for any replies.

Have you tried to do the experiment using different thermometer?

Did you use the same solutions others did?

Yeh we changed our thermometers and used the same exact chemicals everyone else was using.
 

1. What is an acid-base reaction temperature conundrum?

An acid-base reaction temperature conundrum refers to the phenomenon where the temperature of a reaction can affect the strength and rate of the reaction when acids and bases are involved. This can lead to unexpected results and make it difficult to predict the outcome of the reaction.

2. How does temperature affect acid-base reactions?

Temperature affects acid-base reactions by altering the molecular movement and collision rate of the reactants. Higher temperatures typically increase the reaction rate, while lower temperatures can slow it down. In some cases, temperature changes can also affect the strength of the acid or base, leading to unexpected results.

3. What factors can influence the acid-base reaction temperature conundrum?

There are several factors that can influence the acid-base reaction temperature conundrum, including the concentration of the reactants, the type and strength of the acid or base, the presence of catalysts, and the overall conditions of the reaction environment (e.g. pressure, agitation).

4. How can we control the acid-base reaction temperature conundrum?

The best way to control the acid-base reaction temperature conundrum is to carefully monitor and adjust the reaction conditions, such as the reactant concentrations and the temperature. Additionally, using a known catalyst and controlling the reaction environment can also help to mitigate unexpected results.

5. What are some practical applications of the acid-base reaction temperature conundrum?

The acid-base reaction temperature conundrum has many practical applications, including in industrial processes and in laboratory experiments. For example, understanding how temperature affects acid-base reactions can help researchers optimize reaction conditions and improve the efficiency of various chemical processes. It can also be useful in understanding and predicting the outcomes of reactions in biological systems, such as in the human body.
