How Temperature Affects The Solubility Of Salt Experiment
Introduction: We are conducting this experiment to identify how temperature affects the solubility of salt. To add on, by making this experiment we could see how temperature affects the solubility of a substance, the maximum number of solute particles that can dissolve in solvent particles. Also, how by changing the temperature we could see how if the solubility of the solute would either increase or decrease. This experiment connects with information we learn in class because of how in class we learned about the two different types of particles in a substance, which are solute and solvent,that in a substance the solute dissolve and could reach a maximum solubility. To add on, in this experiment we are finding the maximum solubility

Question:
How does the water temperature affects the solubility of salt.
Hypothesis: If the water temperature increase, then the solubility of salt increase because in wps.prenball.com stated that most solubility of solid decrease as the temperature decrease. So, if we make the temperature colder than, the solubility of salt will decrease.
Variables:
Independent variable: Temperature of the water.
Dependent variable: Milliliter of salt.
Constants: Bath, small beakers, and big beakers, stirring sticks.
Control group: The water with zero salt.
Materials:
2x Big beakers
2x Small beakers
2x Stirring sticks
2x Thermometer
1x Cup of table salt
1x Spoon that can hold 5ml of salt
Procedures:
Step 1- Put 300ml of water in each two beakers to form a water bath to make the temperature the same.
Step 2- Use the syringe to get 30 ml of water from the big beaker.
Step 3- Place the water from the syringe to the small beakers. Step 4- Place the thermometers in both of big beakers each to check if the temperature stays the same.
Step 5- Add 5 ml of salt in the small …show more content…
During our experiment we might have came across some errors as we go through the experiment. Such as, some human errors like, reading the thermometer wrong as the actual temperature was higher or lower than the number we thought it was.
To add on, another error from our experiment is the way we use the stirring stick as we did not mix the salt and water properly and started to think that it has reached its climax.Therefore, there are some errors that exist in our experiment.
To improve and minimize error for this experiment in the future is, by being careful at looking at the thermometer and to avoid other human errors in the process. To add on, another way to improve the errors is by taking time to mix the mixture as I mix it at least for 3 min just to make the salt dissolved. Also by checking the temperature at the end of the mixture just to make sure the temperature stay the same so the solubility would not change during the
