Name Date Period MINI LAB NEUTRALIZATION REACTIONS Background

Name _____________________ Date __________ Period ____ MINI LAB: NEUTRALIZATION REACTIONS Background Information Mini labs are designed to take only one period, and to get the entire class to involved in some rapid-fire science. You’ll hone your skillz in designing an experiment in a limited amount of time, as well as collecting data in an organized way. This particular lab is on neutralization reactions. This is a reaction that happens when a base and an acid are mixed together. The product of this reaction is water and carbon dioxide. The sodium may also mix with chlorine or other chemicals in the water to make salt. The base that we will use today is sodium bicarbonate, and the acid is acetic acid. Check out the equation below: Na. HCO 3 + CH 3 COOH H 2 O + CO 2 We’re going to use the scientific process to see what we can do to affect this reaction. You’ll have to design your own data table to collect your data for each experiment. You’ll only need ONE PER GROUP. Procedure PART I: TEMPERATURE Write a hypothesis for what you think will happen if we lower the temperature of the vinegar in the reaction. Put in WHY you think so! Hypothesis: Experimental Design: Conclusions: PART II: VOLUME Write a hypothesis for what you think will happen if we change the volume of vinegar added. Why? Hypothesis: Experimental Design: Conclusions:

PART III: OUTSIDE MATERIALS OR COMPOUNDS Write a hypothesis for what you think will happen if we add another material or compound to the reaction. Again…. . why? Hypothesis: Experimental Design: Conclusions: PART IV: SALINITY Write a hypothesis for what you think will happen if we change the salinity of the vinegar before adding it. We will do this by adding sodium chloride to the vinegar. You guessed it…why? Hypothesis: Experimental Design: Conclusions: PART V: DILUTION Write a hypothesis for what you think will happen if we dilute the vinegar before adding it. Gosh…why? Hypothesis: Experimental Design: Conclusions:
