Adding Baking Soda To Vinegar

Combining Chemicals

Combining Chemicals

James Yan

Purpose:

• To describe the changes that occur when various chemicals are combined in a beaker.

Materials:

• 1 large test tube
• 10mL of water
• 20mL of vinegar
• 3 raisins
• 5g or 2 scoop of baking soda

Procedures:

• Pour 1omL of water into a large test tube.
• Add 20ml of vinegar.

*Record Observations

• Add the raisins.

*Record Observations

• Slowly add 5g of baking soda.

*Immediately record observations at 1 minute, 3 minutes, and 5 minutes.

Data and observations:















Questions:

• The different changes I observed in the beaker were: particles floating towards the surface, raisins having bubbles around them, and water rushing up when adding baking soda to water with vinegar.

• The solid baking soda was starting to bubbling and dissolve in to the water.

• The raisins were floating then sinking after a few seconds, then they were less frequently floated and sank after a while.

Conclusions:

• From this lab, I learnt that when adding water to vinegar, it will not change the water's color, also that raisins will starts to float them sink when baking soda was added to the water with vinegar, and adding baking soda to water with vinegar will make an chemical reaction that will lead the water to bubble and rush up.
