"Solubility of different substances in water" Dissolution PPT courseware

Guess: Which one has the strongest dissolving ability in water, salt or baking soda?

Same conditions:

the same amount of water

Same amount of salt and baking soda per serving

Stir simultaneously

experimental method

Add the same amount of salt and baking soda to the water each time. Wait until the first portion of salt or baking soda is completely dissolved before adding the second portion. Until it can no longer be dissolved, compare again.

experiment plan

Experimental topic: Comparison of the solubility of salt and baking soda in water

My guess:…

Experiment type: comparative experiment

Same conditions: Same amount of water, same amount of salt and baking soda per portion, all stirred at the same time.

Change the conditions: add salt and baking soda respectively

Experimental method: Add the same amount of salt and baking soda to the water each time. Wait until the first portion of salt or baking soda is completely dissolved before adding the second portion. Until it can no longer be dissolved, compare again.

Open a bottle of soda, use a syringe to suck out about 1/3 of the tube, and then seal the mouth of the tube with a rubber stopper.

1. Observe the liquid in the syringe

2. Pull out the plunger of the syringe and observe the liquid in the syringe.

3. Push the plunger of the syringe inward and observe the liquid in the syringe

Combine the knowledge learned to explain the dissolution phenomenon in life

Use an oxygen pump to add oxygen to the fish tank. The oxygen will dissolve into the water in the fish tank.

When making tea, the boiled water turns green. The substances in the tea dissolve into the boiled water.

Putting iodine particles into colorless and transparent alcohol turns into yellow iodine. The iodine dissolves into the alcohol.
